Abstract

This paper presents a ZVS PWM inverter with a three-level PWM control strategy. This approach yields an almost sinusoidal load current and a pulsed output voltage without low order harmonic contents, consequently with low harmonic distortion. The proposed topology minimizes the voltage and current stress on the inverter switches. A complete analysis, simulation and experimental results are presented in this paper
