Abstract
An electrosurgical generator includes: a power supply configured to output a direct current; an energy metering stage including at least one metering switching component operated by a metering switching waveform, the energy metering stage configured to generate a metered energy packet from the direct current; a power converter coupled to the energy metering stage, the power converter including at least one power switching element operated by a power switching waveform, the power converter configured to generate a radio frequency half cycle based on the metered energy packet; and a controller coupled to the power converter, the controller is configured to modulate the metering switching waveform and the power switching waveform.
