Abstract

A novel zero-voltage-switching pulse-width-modulation (ZVS-PWM) interleaved boost dc/dc converter is proposed in this paper. The proposed converter combines the conventional pulse-width-modulation technique, soft commutation technique to promote the circuit performance. The proposed converter uses two boost dc/dc converters with interleaved operation to increase the output power and reduce the input ripple current and output ripple voltage. Comparison with conventional interleaved boost dc/dc converter, the proposed converter has not additional voltage stress on main switches. A ZVS-PWM auxiliary circuit is configured in the presented dc/dc converter to provide the ZVS function on main switches and auxiliary switches and improve the problem of switching losses and EMI. A prototype has been implemented in laboratory to verify circuit theory.
