A zero-current, synchronous switching waveform 800 is provided for a three-phase, wye-connected H-Bridge to power an electric motor. The switching waveform 800 includes two notches 850 per cycle on the switching waveform provided to each of the semiconductor switches to minimize total harmonic distortion and switching loss. Positioning of the notch 850 with respect to the zero-current crossing is optimized to reduce switching loss and minimize total harmonic distortion. |
