摘要：
An electrosurgical generator includes: a power supply configured to output a DC waveform； a current or voltage source coupled to the power supply and configured to output current； and a power converter coupled to the current source. The power converter includes at least one power switching element operated at a switching waveform and configured to generate a radio frequency waveform based on the energy from the current or voltage source. The radio frequency waveform includes at least one pulse having an overshoot peak. The electrosurgical generator further includes a clipper circuit coupled to the current source and the power converter, the clipper circuit configured to generate a clipping voltage to clip the overshoot peak； and a controller coupled to the power converter and configured to modulate the switching waveform to generate the radio frequency waveform.
