Abstract	A zero-voltage-switching pulse-width-modulation (ZVS-PWM) interleaved transformer-isolated boost dc/dc converter with a simple ZVS-PWM auxiliary circuit is proposed in this paper. The proposed interleaved transformer-isolated boost dc/dc converter can provide a high step-up voltage ratio with a simple and compact configuration. And, the proposed converter uses a simple ZVS-PWM auxiliary circuit to provide ZVS function in main switches. Thus, except for the switch in the section of ZVS-PWM auxiliary circuit, all power semiconductor devices in proposed converter operate at ZVS turn on and turn off. The switch in the section of ZVS-PWM auxiliary circuit operates at zero-current-switching (ZCS) turn-on and turn-off. Besides operating at constant frequency, the proposed converter has no voltage stress and current stress on the main switch compared to the hard switching converter counterpart. Auxiliary components rated at very small current are used. The principle of operation, theoretical analysis, and experimental results of the proposed ZVS-PWM interleaved transformer-isolated boost dc/dc converter, rated 800W and operated at 40 kHz, are provided in this paper to verify the performance.
