When conventional resonant converter is applied in high output voltage power supply, the ratio of the transformer is usually very large, and the voltage stress on the filtering components is too high. In order to solve this problem, a symmetric multiplier is applied in the conventional resonant converter and composes the resonant converter with multiplier.(More)
This paper introduces a new topology - parallel resonant converter with multipliers (PRCM), which is a good choice in high voltage applications, such as TWTA power supply. The operating principle of PRCM is analyzed in detail. Design guideline is presented. Then a design example in a TWTA power supply is introduced. At last the conclusion is given
In this paper, the technique of active clamp is applied in ZVT boost converter and forms active clamp ZVT boost converter. This converter is not only simple in topology but also achieves ZVT in both the main switch and the auxiliary switch. The boost diode turns off naturally and there is no reverse recovery loss. Current of the boost inductor flows in(More)
