System Level Real-Time Simulation and Hardware-in-the-Loop Testing of MMCs

Energies, 2021
In this paper we present an approach for real-time simulation and Hardware-in-the-Loop (HIL) testing of Modular Multilevel Converters (MMCs) that rely on switching models while supporting system level analysis.

Hybrid Modular Multilevel Converters for High-AC/Low-DC Medium-Voltage Applications

IEEE Open Journal of Power Electronics, 2023
With ever-increasing power-density requirements, technologies such as energy storage systems and electric-vehicles can benefit greatly from interfacing medium-voltage (MV)-AC grid like 13.8kV or 30kV using high-AC/low-DC voltage converter.

Sliding Mode Control of the Modular Multilevel Converter

IEEE Transactions on Industrial Electronics, 2019
The modular multilevel converter (MMC) has become the most promising converter topology for medium- and high-power applications. In this paper, a sliding mode control (SMC) based method is proposed for the MMC. Based on analysis of the system dynamics under the proposed control method, relations among control parameters and their validity conditions ...

Design and Operation of a Hybrid Modular Multilevel Converter [PDF]

IEEE Transactions on Power Electronics, 2015
This paper presents a hybrid modular multilevel converter (MMC), which combines full-bridge submodules (FBSM) and half-bridge submodules (HBSM). Compared with the FBSM-based MMC, the proposed topology has the same dc fault blocking capability but uses fewer power devices hence has lower power losses.
