The embodiments of the present invention provide a clamp protection circuit, a resonant circuit, and a converter. The clamp protection circuit is configured to perform clamp protection for a circuit to be clamped, and includes: a first clamp diode, a second clamp diode, and a clamping device, where the first clamp diode is connected in series with the second clamp diode to form a bridge arm; the first clamp diode and the second clamp diode are connected with the circuit to be clamped; and the clamping device is connected in series between a midpoint of the bridge arm and the circuit to be clamped. The embodiments of the present invention further provide a resonator circuit and a converter both including the clamp protection circuit disclosed herein. In the technical solutions of the present invention, the clamp protection circuit uses only one clamping device to implement clamping for two resonant capacitors in a symmetric half bridge, thereby reducing the number of clamping devices required, and reducing the cost of the clamp protection circuit and the space occupied by the clamp protection circuit. |
