Analysis of high‐frequency PWM techniques suitable for resonant inverters

Abstract

Special Pulse-Width-Modulation (PWM) techniques capable of realizing true PWM operation of quasi-resonant DC-link inverters are presented. These techniques provide an increased value of the lowest switching time for higher carrier frequencies. The harmonic performances are extensively studied by simulation in comparison with conventional Space- Vector Modulation and a simple algorithm for real-time implementation is developed.
