This paper presents a new strategy for the analytical determination of the natural voltage balancing dynamics of three-phase flying capacitor converters. The approach substitutes double Fourier series representations of the pulsewidth modulation switching signals into a nonlinear transient circuit model of the three-phase converter.

Capacitor Voltage-Balancing Techniques for a Multipulse Rectifier With Active Injection
IEEE Transactions on Industry Applications, 2009Two techniques are presented to balance the filter capacitor voltages of a multi-pulse rectifier with active injection operating on a variable frequency supply. The active injector consists of a low-rated, bidirectional switch that modifies the behaviour of a 12-pulse rectifier at either low or high-frequency , resulting in 24-pulse or multi-level PWM ...

MMC Capacitor Voltage Balancing Strategy Based on Carrier Rotation
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018Modular multilevel converter (MMC) is one of the most potential converter structures for medium/high power/voltage applications. Since the electrical energy is stored in the capacitances of its sub-modules during the operation of the MMC, the output power quality is directly related to the capacitor voltage.

A Sort Method of Balancing Capacitor Voltage of MMC
2019 18th International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES), 2019The sub-module voltage sharing of modular multi-level converters is beneficial to reducing switching losses and eliminating DC side circulations, which has attracted the attention of experts and scholars at home and abroad. Based on the quick selection sorting algorithm, this paper studies the grouping sorting of Modular Multilevel Converter (MMC ...
