This paper proposes a high-efficiency single-phase three-level bidirectional inverter. The proposed inverter has a three-level power switching circuit. It can reduce switch voltage stresses with low harmonic components. It has common-mode capacitors at the ac-filter to suppress the ground leakage current for high power quality. Its circuit operation and control strategy are described. Its common-mode...
This paper presents a novel converter based on the Dickson voltage multiplier for high voltage applications. This converter will have two Dickson chains connected differently to improve the original Dickson voltage multiplier. The main advantage of this converter is that the stresses on the capacitor will be reduced by half, and the output voltage ripples are reduced. The required energy storage of...
Computer simulation is a basic tool in future power engineering education because it allows a better understanding of the various electrical phenomena without the need to make contact with a real system. The achievement and use of simulators contribute to the improvement of electricity supply security taking into account the basic idea that one of the utmost important factors in the electric power...
In this paper, splitting of peak switch voltage by series connected transistors in the class E inverter is proposed. In this method, peak switch voltage of class E inverter is reduced to half of conventional because shunt capacitor voltage is divided by two switches. Key feature of this method is that drive signal source of each switch can be grounded. Namely, transformer is not required in this method...
Power circuits must operate within safe limits to assure long-term reliability and prevent catastrophic failure. However, manual calculation of circuit operating conditions is both laborious and often inaccurate, and breadboard tests can be difficult and time consuming. This paper describes new CAE techniques to automatically evaluate the operating conditions of the components in a power circuit by...
