摘要:This paper highlights a hybrid multilevel inverter for A.C electrical drives. In recent days multilevel inverters has become very popular for motor drive applications of industry .Multilevel pulse width modulation inversion is an effective solution for increases the level number of the output wave form and thereby dramatically reduced to the harmonics and total harmonic distortion. In conventional methods, the need of converters to supply the cells of reversible multilevel converters increases the cost and losses of such inverters. In this new topology the output waveform consists of SVdc; S-number of stages and the associated number of level equal 2s+1 � 1. The output waveform has 15 levels. Moreover, the stage with higher DC link voltage has lower switching frequency and thereby reduces the switching losses. Comparison of conventional results will be presented
