    This paper proposes a robust decoupling current control system to magnetic saturation phenomenon using an extended flux observer for synchronous reluctance motors (SynRMs). SynRMs possess considerable magnetic non-linearity, which gives rise to the difficulty in highly accurate decoupling current control. Hence, to realize robust decoupling current control system to magnetic saturation phenomenon, inductance profiles need to be found at various current points for driving SynRMs. This method, however, requires to prepare highly accurate look-up-table of inductances in advance. This paper proposes robust decoupling current control system to magnetic saturation phenomenon without the table of inductances. The proposed method employs the extended flux observer for the realization of robust decoupling control. In addition, the extended flux observer suitable for proposed method is discussed by analyses of bode diagram. Finally, experimental results show the feasibility of the proposed method in this paper.

    In this circuit, a UWB LNA circuit with new input stage is proposed. In this scheme, a combination of coupled inductors and a new structure based on notch filter in input stage is utilized. As a result, the input stage is able to easily reject in-band and out-band interference with 43.2 dB and 25.1 dB respectively. This input stage is applied in an LNA. The simulations verify that the LNA has a peak gain of 25.9 dB in 3.1-4.8 GHz and a peak gain of 18.62 dB in 6.1-10.6 GHz frequency band while minimum NF in mentioned frequency bands are 1.33dB and 1.8 dB, respectively. This circuit rejects in-band and out-band interference 60.3 dB and 26.4 dB, while LNA core consumes 14.59 mW DC power from 1.8 V power supply. The input reflection coefficient (s11) is less than -8.8 dB over low and high frequency band since worst value of IIP3 over entire bandwidth is -23 dBm which occurs at 3.1 GHz. View full abstract»

    The paper shows the implementation of digital circuit design using ultra-low power logic components. Fundamentals of Source coupled logic (SCL) gates are used with running at sub-threshold regime with the purpose of achieving low power consumption while keeping a satisfactory output swing. The digital system designed for this paper are 4-by-4 array multiplier and a fifty-fifth order FIR filter. The paper also includes modification of an STSCL (sub-threshold source coupled logic) inverter by adding controllable voltage-level feature to it, in order to minimize overall leakage current flow, including both gate and sub-threshold leakage. The modified STSCL inverter has been tested and simulated on a seven-stage ring oscillator design. The rest of the results for the designed digital systems are obtained by separate implementation of the circuits with CMOS and STSCL respectively. Simulations have been performed at similar supply voltage to observe the differences in power consumption. Consumption for the proposed technique came at nW range. All measurements are shown for both 45 nm and 65 nm process technology, with scaling of the supply voltage to an achievable minimum value of 0.4 V. View full abstract»

    Electrical conductivity measurements have been widely used in characterizing the cementitious materials. In mature stages, the influence of interface conductivity to the overall conduction was relatively small. However, its contribution during early hydration is still questionable. This paper calculated the interface conductivity during the first 24 hrs of hydration at elevated temperature and pressure up to 65°C and 3000 psi. The effect of elevated temperature to conductivity measurement is successfully corrected. Johnson equation is employed to predict the interface conductivity of pore-solid particles. The microstructural parameters that are used in the equation are estimated from the proposed particle expansion model. These calculation outcomes have a good agreement compared to the MIP measurements. The results showed that the interface conductivity grew slightly with the progress of drying. Its contribution to the bulk conductivity is relatively very small of about factor 6 in orders of magnitude. Hence, the influence of interface conductivity to the overall conduction might be disregarded during cement's early hydration. View full abstract»

    A new hardware strategy is proposed to increase the reliability of the Switch-Ladder multi-level inverter against short-circuit (S.C.) faults in the H-Bridge and main switches' Blocks. The strategy includes passive and active bypassing. Passive bypassing approach hires fuses in series-connection with the ladder`s steps. Instead, in the active method, relays are replaced the fuses and receive commands from a controller that monitors the short-circuit failures continuously. When a switch fails in short circuit behaviour, the ladder contains the failed switch is converted to open-circuit (O.C.). Owning to the ability of Switch-Ladder multi-level inverter to tolerate open-circuit faults due to its configuration and switching strategy, reliability is increased against short-circuit failures through inverting the short-circuit to open-circuit. At last the experimental result validates the claims. View full abstract»

    In this paper, a single-phase DC power supply based on single-phase matrix converter (SPMC) with reduced number of switches is proposed. In the proposed approach, only six switches of the typical SPMC topology are used to convert the voltage 240 Vrms (50Hz) input to a 12 VDC DC link. In the proposed topology a current control loop is used to ensure that the supply current waveform is continuous, sinusoidal and in-phase with the supply voltage resulting in high input power factor with low total harmonic distortion (THD) level. Therefore, the input currents are of a high quality and devoid of low frequency harmonics under varying load conditions, inherently. Simulation results verify the feasibility of the proposed converter. View full abstract»

    This paper presents the simulation results of the Cascaded H-Bridge Multilevel Inverter (CHMI) with various distance of the electrodes gap in liquid food sterilization using pulsed electric field (PEF). The utilization of the difference gap between the electrodes allow the system to reduce the applied voltage of the HVDC power supply, while fulfilling the requirements for effective liquid food sterilization. Thus it can reduce power consumption and will reduce cost. In this paper, the CHMI circuit has been simulated using MATLAB/Simulink and the distance of the electrodes gap has been simulated using Quickfield simulation software. Peak output voltage 1.2 kV, 2.4 kV and 6 kV with gap distance 0.1 cm, 0.2 cm and 0.5 cm respectively has been obtained in which the values can produce electric field strength of up to 12 kV/cm. All of the specifications meet the requirements for liquid food sterilization, particularly inactivate saccharomyces cerevisiae spoilage microorganisms in pineapple juice. View full abstract»

    The need for regulated, non inverting, constant output voltage from a variable input is on the rise. In this paper, a novel intermediate digital combination mode control is introduced along with real time buck boost converter. So that the cost, efficiency, reduction in the ripple content and output voltage can be enhanced. In conventional control method of buck boost converter, a direct transition from buck to boost mode, produces unwanted spikes in the output voltage. Therefore, designing buck boost converter with improved transient response considerably reduces the spikes, which appear in the conventional output. While this method eliminates the direct buck boost mode operation, it introduces an intermediate combination mode consisting of several buck modes, followed by several boost modes. The introduction of intermediate combination mode results in improved efficiency and reduction in ripple content of the output voltage. View full abstract»

    Distributed energy resources (DERs) such as micro turbine, wind turbine, fuel cell, photovoltaic system and so on, which are high-efficient, high quality and high reliable electrical sources, are been able to create flexible control on power generation during the islanded mode operation of micro grid by power-electronic interface. Performances of two types of inverter controller (PQ controller and VSI controller) show the important role of each model in balancing and power sharing within the islanded network. PQ controller prepares constant active power at specified power factor and VSI controller regulates frequency and voltage through system. This paper is prepared to model two kinds of controller and then investigated the role of controllers through changing load demand and output power of DERs during the islanded network. Moreover appropriate method for handling DERs such as PQ and VSI controller will be proposed in a simulation program which is developed using MATLAB® for one case study. The results are shown and compared in an abbreviated manner. View full abstract»
