| Abstract: | Phase shifted full bridge converter (PS FB converter) utilizes leakage inductance of main transformer and output capacitor of power switches to realize zero voltage switching (ZVS) of power switches and PWM control without any snubber circuit, which is simple both in topology and in control and is suited for middle to high power dc to dc conversion applications. This paper analyzes the principle of PS FB converter, discusses the differences of the realization of ZVS for leading leg and lag leg. Secondary duty loss is the peculiar characteristics of PS FB converter. The simulational and experimental results are also given. |
