In this paper, an interleaved zero-voltage switching(ZVS) two-switch forward(TSF) converter employing the phase-shift control technique is proposed. Since the proposed converter is based on the TSF topology, it has no chance to be a short circuit causing device failure. Furthermore, the interleaving operation of two TSF converters reduces the output filter size. In addition, by e employing the phase-shift control technique on the common clamping diode structure at the primary side, all primary switches can be turned on under ZVS condition. The operational principle, theoretical analysis, and design consideration are presented. To confirm the performance of the proposed circuit, experimental results from a 480W, 100㎑, and 400 V to 48 V prototype are presented.
