In this book the performance of hybrid fifteen-level and twenty five-level Inverters is investigated. The objective of the presented book is to simulate hybrid fifteen-level and hybrid twenty five-level Inverters in MATLAB/Simulink, and experimentally validate through HIL Simulation the power quality of the inverter from load side. In the proposed schemes, a hybrid fifteen-level inverter is achieved by connecting one end of the open-end winding induction motor (OEWIM) with FC-based hybrid five-level inverter and the other end is connected to a symmetrical 3-level inverter & hybrid twenty five-level inverter is achieved by connecting one end of the OEWIM with FC-based hybrid five-level inverter and the other end is connected to a symmetrical 5-level inverter. A level-shifted triangular carrier-based space vector pulse width modulation (SVPWM) algorithm is used on the RT-Lab real-time controller to generate gate pulses for the IGBTs of designed inverters. Balancing of the capacitorvoltages is achieved by selecting the appropriate switching states from the available redundant switching states.
