Interleaved zero voltage switching forward converter with less switches
An interleaved zero voltage switching (ZVS) forward converter with less switches is presented. Two forward converters with active clamp technique are adopted in the circuit to achieve interleaved pulse-width-modulation (PWM) operation and load current sharing.
