Modulation Strategy with a Minimal Number of Commutations for a Five-Level H-Bridge NPC Inverter

Modulation Strategy with a Minimal Number of Commutations for a Five-Level H-Bridge NPC Inverter

In this paper, a so-called OPTimized Pulse Width Modulation (OPT-PWM) strategy with a minimal number of commutations for a multilevel converter (MC) is proposed. The principle is based on the reduction of the number of switch commutations by removing the unnecessary ones for each voltage level trans...
