A circuit for producing an arbitrary defibrillator waveform using switching techniques which reduce the usual high current or high voltage stress on the switching element. This allows existing semiconductor devices to be used in an application previously closed to them. The result is a defibrillator able to produce desirable rectangular waveforms without the waste of energy found in existing approaches. This allows the use of a smaller energy storage capacitor for a given delivered energy. The application discussed here is a cardiac defibrillator but the techniques presented could be applied to other power conversion situations.
