Abstract:
Various examples related to sinusoidal pulse width modulation (SPWM) techniques for harmonic and electromagnetic interference (EMI) noise suppression are provided. In one example, a method includes applying a DC offset to a sinusoidal modulation waveform to change an average duty cycle of a switching circuit; and controlling switching of an array of switches of the switching circuit based at least in part upon the offset sinusoidal modulation waveform and a carrier waveform, thereby reducing total energy. In another example, a system includes a switching circuit with an array of semiconductor switches that control application of a voltage source to a load; and controller circuitry that can control switching of the array of semiconductor switches by applying a DC offset to a sinusoidal modulation waveform to change an average duty cycle of the switching circuit.

Claim (Index 13):
The system of  claim 11 , wherein the modulation index is adjusted to achieve a defined THD (total harmonic distortion).
