Converter with half-bridge circuit

The invention provides a converter with a half-bridge circuit. The converter comprises 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 coupled to the first switch and the second switch and is configured to generate a first control signal for controlling the first switch to be turned on and turned off and a second control signal for controlling the second switch to be turned on and turned off. When the converter is started or restarted, a first duty ratio of a first pulse used for controlling conduction of the first switch of the first control signal is less than 50%, and a second duty ratio of a second pulse, used for controlling the conduction of the second switch, of the first control signal is greater than 50% after the first pulse, used for controlling the conduction of the first switch, of the first control signal is ended. 本发明提供一种具有半桥电路的转换器。转换器包括一电压源、一第一开关、一第二开关、一第一谐振电容、
