摘要： In one implementation, a power converter with over-voltage protection includes a power switch coupled to a power supply through a tank circuit, and a control circuit coupled to a gate of the power switch. The control circuit is configured to turn the power switch OFF based on a current from the tank circuit, thereby providing the over-voltage protection to the power converter. In one implementation, the power converter is a class-E power converter. In one implementation, the control circuit is configured to sense the current from the tank circuit based on a voltage drop across a sense resistor coupled to the power switch.
