Neutral point voltage level stabilization and DC link capacitors voltage balance in neutral point clamped multilevel inverters

2016 11th International Conference on Industrial and Information Systems (ICIIS), 2016
The Neutral point clamped (NPC) inverter has unbalancing problems of neutral point voltage and DC link capacitors voltages, generally dc link capacitor voltage unbalance leads to neutral point voltage unbalance. In this paper neutral point voltage is balanced using sine PWM associated with phase shift technique.

Neutral-point voltage balance control and oscillation suppression for VIENNA rectifier

2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017
In view of a three-phase/level boost rectifier, the performance of VIENNA rectifier is affected by the neutral-point (NP) voltage unbalance and oscillation. A novel strategy of zero-sequence component injection to balance the neutral-point voltage and suppress oscillation for VIENNA rectifier is proposed in this paper.

Control of a four-level active neutral point clamped converter with neutral point voltage balance

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
In this paper, a carrier-based modulation method with optimal zero-sequence signal injection has been devised to modulate the converter and regulate the DC-link neutral points' voltages of a four-level active neutral point clamped (ANPC) converter. With the proposed control strategy, the two neutral points' voltages can be well controlled with a back ...
