Fuzzy Logic Controlled Cascaded Buck Boost Converter Using Multilevel Inverter System

摘要

Cascaded buck-boost converter with multilevel inverter (CBBCMLI) is an alternative system between DC source and Induction motor. This paper investigates closed loop response of cascaded buck boost converter multilevel inverter system with PI and Fuzzy logic controllers. The aim of theproposed converter system is to maintain constant speed of the induction motor drive circuit modules are developed for PI and FL controlled systems. The matlab results obtained show an improved dynamic performance by employing fuzzy logic controller. The hardware is fabricated and tested.The hardware results of CBBCMLI are compared with the simulation results.
