DC Link Voltage Balancing of the Active Front-End for the Extreme Fast Charging Stations
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020One of the most important challenges of the extreme fast charging (XFC) stations is to balance the DC link voltages of the active front-end (AFE). The multilevel cascaded H-bridge (CHB) converter is a great topology for the AFE applications due to the high power density, low total harmonic distortion (THD), and a low number of active and passive ...

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), 2017A 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 ...

Asymmetrical DC link voltage balance of a cascaded two level inverter based STATCOM
TENCON 2010 - 2010 IEEE Region 10 Conference, 2010Voltage unbalance is one of the main limitation of cascaded based multilevel STATCOM. This paper presents a simple control strategy for the voltage balance of a cascaded two level inverter based STATCOM. The topology consists of two conventional three phase two level inverters connected in cascade.

A study on the DC link voltage balancing for power conditioners based on cascaded H-bridges
8th International Conference on Power Electronics - ECCE Asia, 2011In medium and high power field, cascade multilevel converter has been paid more attentions to research and application. When the cascade multilevel converters compensate reactive power and harmonic current, the control of the floating capacitor voltage has been being a hot research topic.
