Zusammenfassung:A converter with half-bridge circuit is disclosed. The converter includes a voltage source, a first switch, a second switch, a first resonant capacitor, a second resonant capacitor, a resonant inductor, a transformer and a control unit. The control unit is configured to generate a first control signal for turning on/off the first switch and a second control signal for turning on/off the second switch. When the half-bridge converter is turned on or reopened, a first duty rate of a first pulse being the first pulse of the first control signal for turning on the first switch is less than 50%, and a second duty rate of a second pulse being the first pulse of the second control signal for turning on the second switch after the end of the first pulse of the first control signal is greater than 50%.
