  • Patent number: 11916487
    Abstract: An asymmetric half-bridge converter is provided. The asymmetric half-bridge converter includes a switch circuit, a resonance tank, a current sensor, and a controller. The current sensor senses a waveform of a resonance current flowing through the resonance tank to generate a sensing result. The controller determines the sensing result. When the sensing result indicates that an ending current value of a primary resonance waveform of the resonance current is greater than a predetermined value, the controller performs a first switching operation on the switch circuit. When the sensing result indicates that the ending current value of the primary resonance waveform is less than or equal to the predetermined value, the controller performs a second switching operation on the switch circuit.
