A New Symmetrical Cascaded Single Phase H Bridge Inverter With Reduced Switch Count

Abstract

An imaginative multilevel inverter topology is presented with the intent of deploy few series connected switches, ameliorate modularity and derogatory voltage stress collate to unremarkable topologies which is published in literature [1] and [2]. This paper mainly focuses on symmetrical configuration. Modified sinusoidal pulse width modulation (MSPWM) technique is developed in this paper with less number of carrier requirement compared to traditional sinusoidal pulse width modulation. This generalized structure and MSPWM technique will give the advantage of less cost of device, compact size.
