Abstract
A high-frequency generator for an electric surgical instrument that treats a living tissue includes a power supply that generates a power, and a resonant circuit that excites a high-frequency signal. The resonant circuit includes a parallel resonant circuit which is connected to the power supply, and a series resonant circuit which is coupled to the parallel resonant circuit and is connected to the electric surgical instrument. The parallel resonant circuit has a higher parallel resonant frequency than a series resonant frequency of the series resonant circuit.
