    By use the taper high voltage windings, the Tesla transformer with compact structure can be built. However, the flashover between coils will occur because of un-uniform of the voltage distribution along the windings. Therefore, researching the voltage distribution of the Tesla transformer, improving the distribution by appropriate method and designing optimized structure of the windings would highly improve repetitive ability of the transformer, which have theoretical and engineering significance for the Tesla transformer's working in reliable and security. In order to study the voltage distribution on the pulse transformer's taper windings, according to the structure of the factual pulse transformer's taper windings, the voltage of a uniform tesla transformer's windings was measured in the paper. It is shown that the voltage distribution of taper winding is not uniform, and the distributed curve of it's interturn voltage is U shape with 100ns pulse. Based on the results, the methods to improve the distribution of the tape winding were bring forwards by measuring and analyzing the voltage distribution of other taper windings with different structure. These results can give some references to interturn insulation designs of Tesla transformer's windings. View full abstract»

    One of the most widely applied devices for repetitive pulse power generator is high-coupling Tesla transformer. The general designing of the high-coupling Tesla transformer is described in this paper. Because of the requirement of high coupling for Tesla transformer, an open-loop magnetic core is employed. In order to reach high reliability of this high-voltage generator, the windings of Tesla transformer (both primary winding and second winding) are set compactly within the insulating gap of pulse forming line (PFL). The parameters of primary and secondary loops have be well-connectedly designed and suitably adjusted. Moreover, as one of the most important components of the TPG700, a high-coupling Tesla transformer, with open-loop magnetic core applied in it, achieved a high efficiency about 83% after optimization. This Tesla transformer can operate on the range of repetition frequency from 1 to 100 Hz. View full abstract»

    The compact, small-sized device based on a pulsed transformer combined with a semiconductor switch is a feasible solution that generates the high-frequency and high-voltage pulse. Compared with other types of transformers, spiral Tesla transformer is much easier to achieve a high output-voltage ratio. By an in-depth analysis of the resonance circuit of Tesla transformer, the expressions of secondary voltage, transformation ratio, peak, and steepness of the primary current are deduced and analyzed in this paper. The development test of a small-size Tesla transformer prototype has been performed. The key electrical characteristics are further measured, estimated, and discussed. The specification parameter selection of the primary semiconductor switch must rely on the characteristics of primary current. Applied to a 6.0 kΩ resistor, the high-voltage repetitive pulse generator based on the Tesla transformer prototype can generate a series of pulses with a peak voltage of 100 kV and a rise time of 40 ns at the repetition rate of 200 Hz. Atmospheric air nonequilibrium plasma can be formed using the developed pulse generator and some typical images are presented. View full abstract»

    Tesla air core transformer has simple insulation structure and can endure higher voltage than the core transformer. Yet its low coupling coefficient and large leakage inductance exert a negative influence on improving its transform ratio. In this study, a new high frequency, high pulsed voltage generator is established. It is composed of an H-bridge inverter and a Tesla transformer. The stray capacitance and the leakage inductance of the Tesla transformer are manipulated to compose a resonant circuit so as to enlarge its output voltage by resonance. In a reasonable design, the resonant frequency of the Tesla transformer will be below 100 KHz, which the inverter with Insulated Gate Bipolar Transistors (IGBTs) can reaches. By comparing the transformer model and the mutual inductance model, the relations between resonant inductance, equivalent capacitance and resonant frequency are established. With the derived equations, the Self- and mutual- inductances calculated by finite element method can be directly used in the analysis of the resonance. Finally a prototype is designed and tested. The testing results have proved the obtained relations. The transformer's fundamental transform ratio is 43, and its tested output can reach 211 times input in resonant operation.

    This present work proposed the compact Tesla transformer which could generate voltage up to 155 kVp with variable frequency between 120-430 kHz. Its size was 1.40 m in length and 0.35 m in width. This Tesla transformer set consisted of a 220V/15 kV transformer, a quenching gap, a capacitor which can withstand the voltage up to 36 kVp and windings used air as insulator. The capacitance was 44 nF which made of polypropylene capacitors. The energy from the storage capacitance was transferred to the primary winding through the quenching gap made of stainless paddle driven by motor while the energy from primary winding to the secondary winding was transferred by magnetic field through air core by wrapping the secondary winding in the PVC pipe. This caused much smaller gap clearance between primary and secondary windings. The output frequency depended on the capacitance of the test object which was usually less than 50 pF. This Tesla transformer was used to test the puncture of pin insulator. View full abstract»

    An approach for producing a long pulse up to 100 ns is presented. The generator based on this approach consists of a Tesla transformer and a set of pulse-forming networks (PFNs). The Tesla transformer is used to charge pulse-forming lines (PFLs) and PFNs which are in parallel. When the voltage increases to a certain value, the main switch will close, and the PFLs and PFNs will discharge rapidly to the load. Therefore, a high-voltage long pulse is formed on the load. The amplitude of this pulse is dependent only on the charging voltage and the matching state between the load and the PFL (PFN). The pulsewidth is determined by the transmission time of the PFL and PFN. The rise time is determined by the working state of the main switch and the impedance of the PFL and is independent of the parameters of the PFN. The PFN is multistage and assembled in series. The single-stage PFN is formed with ceramic capacitors placed between two unclosed annular plates. The total series impedance is equal to the sum of every single-stage PFN's impedance. A nine-stage PFN is used in the generator, and the total impedance is 40 Omega. Experimental results show that a high voltage of an amplitude of 300 kV, current of 6.9 kA, and duration of 110 ns is obtained at a repetition rate of 10 Hz, with a rise time of approximately 7 ns.

    Summary form only given as follows. In very high current applications (many hundreds of kA), Multi-channel triggering is critical for reduction of switch inductance, increasing high peak current switching capability and switch life time. For this, applying a high voltage pulse as quickly as possible to trigger the electrode in order of kV/nS is necessary. We utilized a pulse generator based on a pulsed resonant Tesla transformer. A 30 kV output voltage, 50 Omega impedance, 20 mJ energy nanosecond rise time pulse has been achieved. The ANSYS finite element package has been used for static analysis of the electric field distribution in the dielectric medium in the transformer to ensure that there is no corona discharge. Also this analysis has been used for prediction of primary and secondary inductance and investigation of the variation of the output voltage. The PFL line is established as a coaxial internal structure into the transformer. A self-breakdown peaking gas spark gap switch has been used to discharge PFL energy into the transmission line. A multi-channel spark between trigger electrode and cathode main electrode has been obtained. The output voltage has been measured with a high frequency capacitive divider probe which has good agreement with the analysis. View full abstract»

Tesla transformer is used to charge PFL and PFN in series. When the voltage increases to a certain value, the primary switch will close and the PFL and PFN will discharge rapidly to the load. Therefore, an electric pulse of a certain width is formed on the load. The amplitude of this pulse is dependent only on the charge voltage and the matching state of the load and PFN (PFL). The pulse width is determined by transmission time of PFL and PFN. The rise time is determined by the working state and the impedance of PFN, and independent of the parameters of PFN. The PFN is multi-stage and assembled in series. The direction of main dielectric flux is axial and the time modulation is angular. The single-stage PFN is formed with two-row ceramic capacitors placed between two aperture annular plates. The total series impedance is equal to the sum of every single-stage PFN's impedance. Moreover, a tested generator based on this approach is developed. For this device, PFN of nine stages is in series, and the total impedance is 40Ω. The high voltage of amplitude 295kV, current 7kA and duration ~110ns is produced at repetition frequency of 10 Hz. And the rise time of voltage waveform is only ~7ns. View full abstract»

    Summary form only given, as follows. Well known are nanosecond HV periodically pulsed generators based on high-coupling Tesla transformers and long coaxial forming lines with oil insulation. Combining Tesla transformer with long forming line allowed substantial increase in its charging efficiency and resulted in production of relatively compact HV generators and high-current electron accelerators with the average power in the range of several hundreds kilowatts. These accelerators are widely applied for HPM pulse production at high pulse repetition rates. Increasing the pulse width of the HV generators requires using longer forming lines. In the case of relatively high-ohmic loads, the problem may be used, alternatively, by utilizing spiral forming lines. This allows an increase in the generator impedance and pulse width, keeping the same stored energy, and with no substantial increase in the generator size. This paper presents a nanosecond periodically-pulsed generator based on a spiral line charged by means of a high-coupling Tesla transformer. At repetition rate of 100 p.p.s., 100-ns, 600-kV pulses were produced in a /spl sim/100-Ohm load. View full abstract»

    Insulation materials used in high-voltage switched-mode power supplies are exposed to high-frequent high voltages. Ageing tests performed with high DC voltages or low-frequency high voltages might not reveal the true ageing effects which take place during rated operation at high frequency. Studies on different voltage source principles have been carried out. Finally the tesla transformer principle turned out to be superior for the purpose of testing the ageing performance of insulating materials under high voltages at high frequency. For this reason a voltage source based on the tesla transformer principle was developed to enable relevant testing. Ageing experiments on plastic foil samples performed up to now have confirmed the suitability of the chosen principle and the reliability of the applied voltage source. Options are available to increase the test voltage level and to modify the test voltage frequency View full abstract»

    In this paper, effects of induced electromotive force (EMF) on coils excited by square waves are shown, as well as how these influence resonance phenomena. The work was based on experimental results, using planar coils and inner ring coils. A priori, the resonance is presented as effects of parasitic capacitances on coils, which through inclusion of external capacitances, is established that the phenomenon of high voltage on output is the sum of responses of the induced EMF added with response to step voltage on rise and fall of the square wave. Consequently, the found results explicate the phenomenon of high energy (or high voltage) in the output of Tesla transformer. View full abstract»

    In order to study the very fast transient overvoltage (VFTO) distribution in the taper winding of a tesla transformer under high-frequency steep-fronted voltage surge, we built a distributed line model based on multiconductor transmission line (MTL) theory. We used a new hybrid algorithm combining finite-element-method (FEM) and interpolation formulas to quickly evaluate the induction coefficient matrix K by utilizing some characteristics of the taper structure. The turn-to-ground and interturn voltage distributions can be obtained by solving the telegraphist's equations in the frequency domain. We measured the voltage distribution inside the taper winding to find some ways to weaken the voltage oscillations. Here, we compare the results with numerical values. View full abstract»

    This paper provides an overview of the response of the tuned secondary circuit of a Tesla transformer, following impulse excitation from the tuned primary circuit. Multiorder oscillatory voltages and currents are energized in the secondary circuit, and research is ongoing to determine the fundamental and higher order modes for various secondary winding configurations, with the aim of developing design techniques that can be used to suppress the generation of the higher order modes. It is anticipated that this will lead to generators which exhibit enhanced spectral purity and which will be better suited to use in electronic warfare applications than conventionally wound Tesla transformers.

    A circuit topology which can prevent the series resonant power supply in a Tesla transformer from damage induced by the reversal voltage on the storage capacitor is presented. The circuit is based on current-limiting resistor and auxiliary capacitor which can restrict the over current in the rectifier of series resonant power supply. Moreover, adoption of the auxiliary capacitor can raise the average power output of the power supply due to the increase of initial voltage on the storage capacitor. When reversal voltage on the storage capacitor is zero and the auxiliary capacitor is one quarter of the storage capacitor, analysis shows the average power output can be raised 33%. Computation of charging accuracy and optimization of current-limiting resistance are also discussed. View full abstract»

    Experimental studies on a designed pulsed power modulator with a compact Tesla transformer in single and repetitive modes from low voltages to high voltages are experimentally carried out in turn. The experimental results are presented and analyzed. The conclusions are shown as follows: (1) the modulator's highest output voltage across a 100 Ω resistive load in single mode is obtained to be 330 kV with 7 ns pulse duration and 2 ns rise-time; (2) the cooling system and gas blowing system are unnecessary and not adopted experimentally in repetitive mode in the case that the number of pulses in a batch is less than or equal to 300, as a result, the volume and weight of the modulator system is reduced; (3) in the range of 300 pulses in a batch, with the increase of the number of pulses in repetitive mode, the average value of the output voltage declines and the pulse-to-pulse instability of the output voltage decreases, at the same time, the decline degree of the output voltage increases and reaches to be stable when the number of pulses in a batch is more than 50; (4) with the increase of the repetition rate, the pulse-to-pulse instability of the output voltage increases, and the average value of the output voltage declines, especially after the repetition rate exceeds 40 Hz; (5) pressurization can significantly improve the characteristics in repetitive mode and the improved level of the characteristics is almost the same for different pressurization level; (6) the pulsed power modulator can steadily output 310 kV for 300 pulses in 40 Hz repetition rate.

    Many modern applications of pulsed power, such as industrial food processing, pollution control and compact radiation sources for the defence industry require a simple, reliable, repetitive table-top high-power source. Although Marx generators are commonly used, a much simpler technical solution is to couple a single high-voltage capacitor with a repetitive and miniaturized plasma opening switch (POS). Loughborough University has recently begun the first investigations into this area of technology, and the paper presents a 300 kV high-power 3.8 Omega/50 ns pulse forming line generator based on Tesla transformer technology that has been designed and recently successfully commissioned. All the high-voltage components required for the generator are described, together with results obtained from the diagnostic tools. The generator is used to drive a miniature and repetitive POS and results from the phase of the experimentation are presented. View full abstract»

    Aspects of design of a multi-sectional Tesla transformer (MTT) presented as a system with three primaries are discussed. Calculation and experimental characteristics of MTT, and its advantages (lower currents in the primary, higher efficiency together with lower duration of the period) in comparison with traditional TT are shown.
