This book provides detail understanding of Neutral Point Clamped inverter and also various Multilevel inverters. The hardware implementation of Neutral Point Clamped inverter with real time simulator is performed. Space Vector Modulation techniques with Nearest Three vector and Symmetrical modulation techniques are used to control the DC-link voltage. An extensive comparison between these techniques for balancing is carried out. The hardware results are demonstrated for the same. An IEEE paper is also published based on the simulation results, titled as "DC-link Capacitor Voltage Balancing in Neutral Point Clamped Inverters using Space Vector Modulation"
