Significance of Capacitor Voltage Balancing in Multilevel Inverter
2019 IEEE International Conference on Innovations in Communication, Computing and Instrumentation (ICCI), 2019In the recent trends, the use of multilevel inverter is rapidly increasing due to its good performance compared to conventional inverter. In this paper, the performance of Nested Neutral Point Clamped Multilevel inverter (NNPC) is presented. NNPC is a Hybrid type of Multilevel inerter which is nothing but the combination of two classical topologies ...
