Analysis of PI and Hysteresis Controlled Cascaded Dual loop Quadratic -Boost-Multilevel Inverter System

Abstract

Quadratic Boost Converter (QBC) finds a place between PV and single phase Multi Level Inverter (MLI) with motor load. In this work, we devise a new QBC between DC source and nine-levels MLI. A Hysteresis Controller (HC) and PI have been considered for the closed loop response of QBC-MLI system. The key finding of proposed system is evaluating and differentiate dynamic response of closed two-loop PI-PI & PI-HC controlled QBC-MLI systems and output current THDs. The computer simulation using MATLAB software demonstrates efficient and dynamic performance of the HC controlled QBC-MLI system. Efficacy of proposed system is authenticated through the simulation outcomes.
