A Study of Three-Level Neutral Point Clamped Inverter Topology
The three-level Neutral Point Clamped (NPC) inverter has become matured and widely used topology in high-power medium-voltage applications due to several advantages associated with it as compared to other available multilevel topologies. This paper presents a brief review on operation of threelevel NPC inverter. Different modulation strategies used in NPC inverter is also discussed. The problem...
متن کاملDirect Torque Control for Three-Level Neutral Point Clamped Inverter-Fed Induction Motor Drive
Direct torque control (DTC) is a control technique in AC drive systems to obtain high performance torque control. The classical DTC drive contains a pair of hysteresis comparators and suffers from variable switching frequency and high torque ripple. These problems can be solved by using space vector depending on the reference torque and flux. In this paper the space vector modulation technique ...

متن کاملSpace Vecor Modulated Three Level Neutral Point Clamped Inverter Using A Single Z Source Network
The Neutral Point Clamped (NPC) three-level inverter with Z-source network is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. This concept can be applied to all acto-ac, dc-to-dc, ac-to-dc, and dc-to-ac power conversion whether two-level or multilevel. However, multilevel inverters offer many benefits for higher power applications. Existing p...
متن کاملH∞ current control strategy for the neutral point of a three-phase inverter
Abstract— In this paper, an H∞ current controller is proposed to maintain a balanced neutral point for a three-phase fourwire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional neutral leg and a split DC link. The neutral point is balanced with respect to the two DC source terminals (as required, e.g., in neutral-pointclamped three-level ...
