Performance Analysis of Cascade H-Bridge Multilevel Inverter Topology With Filter Circuit and Without Filter Circuit

Abstract

Multilevel inverter is a modified version of inverter. Multilevel inverter recently emerged in the area of high power and medium voltage application. In the last few decades, the great innovation has been done to improve the inverter performance, and it is challenging even today. The multilevel inverter performance is examined by total harmonic distortion and component required. In multilevel, as level increases, the total harmonic distortion value decreases, but the number of components required and driver circuit increases that make the circuit more complex and also the effect on cost. So, the challenge is to balance the bridge between cost and total harmonic distortion. This chapter simulates the various levels of conventional cascade H-bridge inverter and new proposed topology of multilevel inverter with using different modulation techniques and with using filter circuit and without filter circuit.
