Estimation of Harmonics for Generating SPWM Based on DSP

Wei Ji, Weixing Lin

Abstract

Aiming at the wide application of SPWM sinusoidal modulation wave in the inverter circuit, the paper presents a method of generating SPWM wave according to an improved equal area algorithm based on digital signal processor (DSP) TMS320F2812, and adopts a particle swarm optimization (PSO) algorithm to estimate the amplitude and phase of harmonics, hence, it can help to choose duty cycle to make the harmonics lower or minimum.
