Voltage Balancing Control in Three Level Diode Clamped Inverter Using Carrier Based Offset Addition

Abstract

Three-level Neutral-Point Clamped (NPC) inverter has become established to be a preferred topology for medium-power motor drive applications operating at several kilovolts. Still several research continues to find solutions to the problem of maintaining a stable neutral-point voltage in the converter. This paper presents the analysis and simulation of a… (More)
