Abstract
A pulse ablation instrument includes a power supply circuit, a pulse switching circuit, a sampling circuit, and a switching control circuit. The power supply circuit is configured to supply power to a load. The pulse switching circuit is connected to the power supply circuit, to regulate a current output by the power supply circuit and flowing to the load. The sampling circuit is configured to sample a current flowing through a power feeding loop of the load and obtain a sampling value. The switching control circuit is electrically connected to the sampling circuit and the pulse switching circuit, and is configured to output a drive signal which controls an operation of the pulse switching circuit according to the sampling value and reduce a duty cycle of the drive signal to reduce an output current of the power supply circuit when the sampling value is greater than a threshold value.
