  • Harmonic inductor for generation of an energy conserving power wave
    Patent number: 4795959
    Abstract: An energy convertor for generating a power output waveform that contains a fundamental sine wave and a controlled amount of the third harmonic wave to eliminate the sinusoidal peaks and to provide a desired flat top at reduced amplitude. The synchronized generation of the third harmonic is achieved in combination with a new inductor that enhances the harmonic in the magnetic path around the inductor.
