The deviation of calculation and experience is within 5.7% in spite of neglecting the output current ripple.

Some converters such as boost, buck-boost, and fly-back have a right-half-plane zero (non-minimum phase system), hence it is difficult for the PID controller to exhibit good performance with load, line variations and parametric uncertainty. In this proposed work, design and implementation of type controllers have been performed by using k-factor approach and two different optimisation techniques (gravitational search algorithm and particle swarm optimisation) for obtaining better stability and performance for a closed loop DC–DC Switched mode boost converter. The closed loop control system has been implemented in real time dSPACE platform. The comparative closed-loop performances of a boost converter with classical, optimised PID and optimised type II/type III controllers have been produced. Simulations and experimental results are provided to demonstrate the effectiveness of optimised controllers for the proposed converter. Design and implementation of optimised type controller for switch mode converters has not been reported earlier in any literature.]]>959389501046<![CDATA[Simplified model and submodule capacitor voltage balancing of single-phase AC/AC modular multilevel converter for railway traction purpose]]>95951959665<![CDATA[Instantaneous current-sharing control scheme of multi-inverter modules in parallel based on virtual circulating impedance]]>959609681067<![CDATA[Evaluation of reverse recovery characteristic of silicon carbide metal–oxide–semiconductor field-effect transistor intrinsic diode]]>i/dt) and junction temperature are major factors affecting the turn-off process of a diode, and are mostly concerned in practical applications. Therefore, in this study, the reverse recovery characteristics of the intrinsic diode are systematically evaluated based on these four factors. The experimental results are presented and discussed. The reverse recovery characteristics of an SiC Schottky barrier diode (SBD) and two types of silicon (Si) p–i–n diode are also presented for a quantitative comparison. In terms of the reverse recovery performance, although not as good as the SiC SBD, the SiC MOSFET intrinsic diode is much better than the Si p–i–n diode.]]>959699761038<![CDATA[Generalisation of an averaged model approach to estimate the period-doubling bifurcation onset in power converters]]>959779881173<![CDATA[Rapid and generalised space vector modulation algorithm for cascaded multilevel converter based on zero-order voltage constraint]]>959899961222<![CDATA[Power transfer using portable surfaces in capacitively coupled power transfer technology]]>2 capacitive surfaces and 32 V source.]]>9599710081289<![CDATA[Voltage sensorless predictive direct power control of three-phase PWM converters]]>95100910181751<![CDATA[Physics-based model of LPT CSTBT including MOS-side two-dimensional effects]]>9510191028765<![CDATA[Repetitive control-based single-phase bidirectional rectifier with enhanced performance]]>95102910361007<![CDATA[Power decoupling strategy based on ‘virtual negative resistor’ for inverters in low-voltage microgrids]]>P/w and Q/E droop control is subject to the coupling and dynamic instability of the real and reactive power control. To address this problem, a novel virtual impedance composed of virtual negative resistor (VNR) and virtual inductor is employed to control the interfaced inverters in this study. The virtual resistance is controlled to be negative to counteract the effect of the line resistance thus ensuring a mainly inductive system impedance. However, it is found in this study that, the grid-connected inverter system may present non-fundamental instability if the line resistance drifts to be smaller than the value of VNR with the basic VNR method. To produce a more stable system when the line parameter drifts, an improved VNR form based on a proportional-resonant structure is proposed. Moreover, an interesting conclusion is obtained that, if the PI voltage regulator and the basic VNR are used, the grid-connected inverter becomes critical stable when the virtual resistance is exactly equal to the line resistance. Experimental results of a low-voltage microgrid consisting of two 6-kW inverters are given to validate the control strategy.]]>95103710441053<![CDATA[Study on the lifetime characteristics of power modules under power cycling conditions]]>T_{j}) cycles contribute little to the lifetime consumption, but with an initial damage the effect becomes noticeable. The original Coffin–Manson accumulation approach is extended for complex mission profiles. The proposed non-linear accumulation model has three aspects: a Coffin–Manson relationship is first established; the thermal resistance degradation is then used to quantify damage accumulation; the effects of the average junction temperature (T_{jmean}) and ΔT_{j} on the rate of degradation are finally included through the parameters of the non-linear accumulation model which also depends on the effect of the present condition of the module. Experiments demonstrate the phenomena and verify the proposed model.]]>95104510521159<![CDATA[Adaptive recursive inverse-based control algorithm for shunt active power filter]]>95105310641626<![CDATA[Trans-switched boost inverters]]>95106510731376<![CDATA[Zero-current-switching bidirectional interleaved switched-capacitor DC–DC converter: analysis, design and implementation]]>95107410821168<![CDATA[Analysis and design of snubber circuit for Z-source inverter applications]]>95108310911064
