摘要: Apparatus for generating a high time-varying AC voltage using low power semiconductors arranged in series bridge circuits, each powered by an independent DC source. At least one bipolar output pulse width modulation circuit and at pair of square wave generator circuits have their outputs added together passed through pass filter to form time-varying, typically sinusoidal, waveform. A first has with relative magnitude 6, second 2 the modulator 1. Additional generators 6 may be increase voltage.
