In this paper, we present selective harmonic elimination modulation strategy for single and three phase differential type buck boost inverter. In this inverter, the electrolytic capacitor is replaced with two film capacitors, thereby increasing the reliability of the proposed converter. Due to the switching technique adapted in this work, the switching losses are reduced as the body diodes are made ineffective and also as the switches operates at high frequency only for the half cycles, the efficiency is improved. The simulation work is further extended to three phase inverter and its performance is noted.
