Zero-voltage switching of a switching element (Q2) is achieved by turning off a switching element (Q1) and then turning on switching element (Q2) while the parasitic diode (DQ2) of switching element (Q2) is turned on. Subsequently, switching element (Q2) is turned off when the current flowing through switching element (Q2) changes from negative to positive (in a direction from the drain towards the source) and the current reaches a prescribed threshold value. Then, zero-voltage switching of switching element (Q1) is achieved by turning on switching element (Q1) while the parasitic diode (DQ1) of switching element (Q1) is turned on. |
