A Hybrid Control Method for Neutral-Point Voltage Balancing in Three-Level Inverters
IEEE transactions on power electronics, 2021Neutral-point (NP) voltage fluctuation is an inherent problem in three-level inverters. Without any control measures, the NP voltage will deviate, and the dc bias and ac oscillation can be observed, which may lead to the failure of power devices and ...

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper investigates two conflictive issues of common-mode (CM) voltage reduction and neutral point (NP) voltage balancing in a three-level neutral-point-clamped (NPC) converter. The amplitude of NP voltage variation under CM voltage mitigation scheme has been derived analytically.

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.

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), 2016In 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 ...
