MMC Capacitor Voltage Decoupling and Balancing Controls

IEEE Transactions on Power Delivery, 2015
A Modular Multilevel Converter (MMC) control system based on converter energy storage is proposed in this paper for two different control modes: active power and dc voltage. The proposed control system decouples the sub-module (SM) capacitor voltages from the dc bus voltage. One of the practical applications is the management of active redundant SMs. A

Capacitor‐voltage‐balancing control for isolated medium‐voltage AC‐DC modular matrix converter

Electronics and Communications in Japan, 2023
AbstractThis paper presents a capacitor‐voltage‐balancing control scheme for an isolated medium‐voltage AC‐DC converter using level‐shifted pulse width modulation (PWM) control of a modular matrix converter (MMxC). The proposed isolated AC‐DC converter is composed of the primary MMxC with level‐shifted PWMcontrol, high‐frequency transformer, and ...

Capacitor Voltage-Balancing Control for Flying-Capacitor MMC without Current Sensors

2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020
This paper proposes a submodule (SM) capacitor voltage balancing control scheme for the flying-capacitor modular multilevel converter (FC-MMC), where current sensors are not used. From the SM capacitor voltages and the half-arm insertion index, the DC and AC circulating currents are estimated, instead of measurement.
