A new method for realizing a zero voltage switching DC-DC converter is proposed. An additional circuit named charging and discharging circuit is introduced to realize zero voltage switching. Efficiency of a DC-DC converter is improved by using the proposed charging and discharging circuit, because variation of inductor current is suppressed. Switching timing for charging and discharging circuit are also explained. The proposed circuit is applied to a boost converter. Efficiency of the boost converter achieves 98.8%.
