Abstract :
A single-phase five level pulse width modulation (PWM) rectifier is proposed. The control scheme is using the sinusoidal PWM technique to improve the power factor and to achieve a lower total harmonic distortion (THD) for the proposed rectifier. The control method is also aimed to obtain a nearly sinusoidal line current. Five-level PWM output is generated at the ac terminal. The proposed topology is verified by a software simulation.
