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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
