초록
In this paper, operation of isolated current-fed full-bridge converter with active clamp is investigated by simulation and experiments. Experimental waveforms show a good agreement with the corresponding simulation results. Further, losses such as conduction loss, turn-on/off loss of MOSFETs and diodes are measured and their characteristics in the converter is addressed. 200W prototype DC-DC converter is developed for verification of the derived operating modes, design rules and loss analysis.
