## Abstract

A novel optimal time-domain technique for pulse-width modulation (PWM) in three-phase inverters is presented. This technique is based on the time-domain per phase analysis of three-phase inverters. The role of symmetries on the structure of three-phase PWM inverter voltages and their harmonic contents are discussed. Numerical results highlighting improvements in the harmonic performance of three-phase inverters are presented
