Abstract
Abstract Pulse Width Modulation is widely used in static power inverters (d.c. to a.c. converters) to control the output voltage and the harmonic content in it. Sinusoidal pulse width modulation is known to produce the least harmonic content in the inverter output. This paper describes a novel control circuitry that generates the three-phase sinusoidal pulse width modulation signals using a single phase sinusoidal reference signal and a triangular carrier signal. The advantages of this circuit are discussed and experimental results are presented
