<P>PROBLEM TO BE SOLVED: To achieve optimum soft switching control without being affected by variations in hardware characteristics of a circuit element. <P>SOLUTION: In a one-way resonance type power conversion device having a switch control section for turning on a main switch when a voltage of an auxiliary capacitor is minimum after an auxiliary switch is turned on, the switch control section detects the timing that the voltage of the auxiliary capacitor is not more than a threshold value after the auxiliary switch is turned on as the timing that the voltage of auxiliary capacitor becomes minimum. <P>COPYRIGHT: (C)2013,JPO&INPIT |
