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

Power Balance for Voltage-controlled PV Generator without Robust Voltage Source

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
Voltage control mode is preferable because of better bus voltage support and low reliance on communication. However, that is difficult to implement on photovoltaic inverter without robust voltage source. Meanwhile, photovoltaic arrays have some power management ability that usually neglected due to the use of MPPT, which in fact damages balanced power ...

Capacitor voltage balancing control for series MMC tap

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
The series HVDC tap based on modular multilevel converter (MMC) has been proposed to provide power supply for rural places. However, most of current capacitor voltage balancing control strategies are not suitable for series MMC tap. In this paper, the principle of power transfer between phases, arms and sub-modules (SMs) in a series MMC are analyzed. A

Variable-Reference Voltage Balancing Control for Four-Level Rectifiers

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
Four-level rectifiers suffer from severe imbalanced capacitor voltages. Taking a hybrid Detroit rectifier as an example, a variable-reference modulation scheme is presented and analyzed in detail. Based on the variable-reference modulation scheme, a closed-loop control strategy is developed for the hybrid Detroit rectifier.
