  • Patent number: 11990840
    Abstract: A control method is disclosed to prevent false triggering of over-current protection. A power converter comprises high-side and low-side switches connected in series between an input power line and a ground line, for driving a resonant circuit to resonate. The power converter includes a detector detecting the resonant circuit to provide a detection signal representing a magnitude of resonance in the resonant circuit. A duty cycle of one of the high-side and low-side switches is detected, and a threshold is determined in response to the duty cycle. An over-current protection is triggered based on the threshold and the detection signal. When the over-current protection is triggered, at least one of the high-side and low-side switches stops providing power to the resonant circuit, and the resonance subsides.
