Abstract :
This paper presents a two-level single phase full-bridge inverter which has four main switches operating at high frequency. In order to reduce the commutation losses and EMI content, each switch uses a stressless commutation cell. The proposed topology works in two levels with sinusoidal PWM modulation. The operating principles, relevant equations and test results are presented. The obtained results validate the proposed inverter
