A simple method for balancing the DC-link voltage of three-level inverters
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002In this paper, a simple control method for balancing the DC-link voltage of three-level neutral-point-clamped (NPC) inverters is presented. The method is based on DC-DC power converter technology. In addition, the proposed topology is enhanced to also improve the NPC inverter's ride-through ability.

Voltage balancing control of a symmetrical nine-phase machine with series-connected DC links
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017This paper explores the possibility of using a nine-phase machine, with three isolated neutral points, in order to produce a high dc-link voltage by cascading three lower voltage three-phase voltage source inverters. Each inverter drives one winding set of the machine. Consequently, used inverter switches and capacitors have three times smaller voltage

Study on the Performance of Cascaded STATCOM Based on DC-Link Voltage Balancing Method
Applied Mechanics and Materials, 2012DC-link voltage balancing method is the key technique of cascaded static synchronous compensator (STATCOM) while safety and reliability is required previously. However, independent control scheme is necessary for each H-bridge in consideration of the voltage balancing strategy, which is different from the assumption of carrier phase shift modulation ...

A control technique to balance the voltage of DC-link for three-level NPC converter
2017 Brazilian Power Electronics Conference (COBEP), 2017This paper proposes a control to balance the voltages of Dc-link for three-level NPC converter. Several relevant characteristics of the converter are addressed, such as voltage capability, harmonic distortion, and power losses. Compared to other techniques, the level of harmonic distortion was lower and the semiconductor losses (conduction and ...

About the DC-link capacitors voltage balance in multi-point clamped converters
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002The multi-point clamped converter (MPCC) represents an interesting technical solution to overcome the limitations in voltage and power posed by the existing semiconductor devices. However, if real power must be delivered to the load, DC-link capacitors exhibit a problematic voltage unbalance, that can be faced in both active or passive ways, that is ...

Common mode-voltage elimination and DC-link balancing for three-level inverter
International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2011), 2011The paper presents the effects and importance of parameters like harmonics and currents that are to be accounted for the satisfactory performance of an inverter. Practically known problems such as common-mode voltage between inverter and load neutral and the dc-link unbalance of source capacitors are affect the performances of the inverter.

Predictive current control and DC-link capacitor voltages balancing for four-leg NPC inverters
2013 IEEE International Symposium on Industrial Electronics, 2013This 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
