A Novel Cascaded Multilevel Boost converter fed Multilevel inverter with reduced switch count

Abstract

ABSTRACT Novel cascaded multilevel converters fed multilevel inverter for the AC load is presented here. In an inverter, total harmonic distortion plays a vital role. With the aim of reducing the harmonic value, the number of levels of an inverter should be increased. This circuit consists of two multilevel converters, two level controllers and two H-Bridge inverters. The advantage of this topology is to obtain more number of levels in an output, fewer significant number of switches, voltage sources and passive components like capacitors and diodes. This circuit could be operated in two ways as symmetric, & asymmetric configurations. As a result of this topology, 19-level output can be obtained. The performance of this circuit is simulated by means of MATLAB, and the hardware result is proved with the simulation results.
