摘要： PROBLEM TO BE SOLVED: To provide a switching circuit control device for a resonant converter that has a DC current output. SOLUTION: A half-bridge consisting of a first transistor Q1 and a second transistor Q2 generates a cyclic square wave voltage for driving a resonant circuit 300 for a resonant converter. A control device 100 has a circuit means 101 adapted to control the half-bridge according to a charging or discharging time period of a capacitor Ct and to synchronize the start time Tstart of a discharging or charging time period of the capacitor Ct that crosses a zero value of the signal Vs representing the current Is flowing in the resonant circuit 300; and additional means 102 and 103 adapted to control switching-off of the first transistor Q1 or the second transistor Q2 at the end of the discharging or charging time period of the capacitor Ct.
