Pulse electric field ablation device

The utility model provides a pulsed electric field ablation device which comprises a pulse generating circuit, a current sensor and a short circuit protection module, the pulse generating circuit comprises a direct current power supply, a relay and two half-bridge circuits forming a full-bridge structure, the positive polarity input sides of the two half-bridge circuits are connected with the positive voltage output end of the direct-current power supply through the relay, the negative polarity input sides of the two half-bridge circuits are connected with the ground, the output ends of the two half-bridge circuits are connected with a load, and the current sensor is used for detecting the output current of the direct-current power supply and feeding back the corresponding voltage. The short-circuit protection module is connected with the pulse generation circuit and the current sensor and used for judging whether the voltage output by the current sensor exceeds a reference voltage or not, and if yes, the rel
