A soft switching interleaved boost DC/DC converter
A novel soft switching 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 soft switching auxiliary circuit is configured in the presented dc/dc converter to provide the soft switching 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.
