CLOSED LOOP CONTROL OF MULTI LEVEL INVERTER USING REVERSE VOLTAGE TOPOLOGY
Journal Title: International Journal of Electrical Engineering & Technology (IJEET) - Year 2019, Vol 10, Issue 2
Abstract
In this paper a new topology with a reversing voltage component is proposed which will improve the multilevel performance by compensating the disadvantages of increased number of components, complex pulse width modulation control method and voltage balancing problem. This topology requires fewer components compared to existing inverter topologies (particularly in higher levels) and requires fewer carrier signals and gate drives. Therefore the overall cost and complexity are greatly reduced particularly for higher output voltage levels. This paper describes the general multilevel inverter schematic and modified circuit having only seven switches for seven- level multilevel inverter using reverse voltage topology. A general method of multilevel modulation phase disposition (PD) SPWM is utilized to drive the inverter and can be extended to any number of voltage levels. The simulation of a modified seven level multilevel inverter using reverse voltage topology is also presented here
