Abstract :
In this paper, the zero voltage switching (ZVS) in active clamp forward converter is investigated. The investigation starts with discussing the basic operating principle of active clamp forward converter (ACFC). The current mode control ZVS ACFC design procedure is also presented in detail. A prototype forward converter with dc input of 16V, output voltage 5V operating at rated output load of 4A and a switching frequency 400 khz is provided to analyse the main mosfet switching waveform under zero voltage condition.
