Abstract

This paper presents a single-phase 3-level PWM inverter to alleviate the harmonic components of output voltage and current under the conditions of identical supply DC voltage and switching frequency to the conventional inverter. Operational principles and analysis are performed, and the switching functions are derived. Deadbeat controller is also designed and implemented for the inverter to keep the output voltage being sinusoidal and to have the high dynamic performances even in the cases of load variations and the partial magnetization of filter inductor. The validity of proposed inverter is proved from the simulated and experimented results.
