Predictive current control and DC-link capacitor voltages balancing for four-leg NPC inverters

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper presents a finite control set model predictive strategy to control the three-phase four-leg neutral-point-clamped (NPC) inverters. The four-leg NPC inverter delivers power to the unbalanced/nonlinear three-phase loads, and it can produce three output currents independently. The proposed method uses the discrete-time model of the inverter and

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.

Method for DC-link voltage balancing for a grid-connected inverter in case of asymmetric operation

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
A grid-connected inverter with energy storage and active DC-link voltage balancer circuit is presented. The system is implemented with two identical 100kW three-phase converters. The operating limits of the system under asymmetric grid currents with the given hardware architecture are considered and solutions for symmetrisation of the DC-link are ...
