| Abstract |
An asymmetrical type zero current switching (ZCS) DC-DC converter with constant frequency voltage control (CFVC) is developed. Not only the main active switches but also the rectifier diodes are operated with ZCS in CFVC. THe principle of ZCS operation in which an overlapping commutation phenomenon is effectively utilized without additional switch is elucidated. From the results, the design criterion of the asymmetrical type ZCS DC-DC converter is studied. The ZCS characteristics such as output voltage regulation and output voltage ripple are numerically analyzed and verified experimentally. From the results, an improved type asymmetrical ZCS converter is proposed. |
