Abstract
An electrosurgical generator is disclosed. The generator includes a power supply operable to generate a DC voltage and a multi-pole, phase-shifted, pulse-width and/or frequency modulated RF output stage coupled to the power supply. The RF output stage includes a plurality of dual-pole circuits, each of the plurality of dual-pole circuits including first and second pairs of switching components. The generator also includes a controller configured to drive the first and second pairs of switching components of each of the plurality of dual-pole circuits at a predetermined phase-shifted frequency.
