Special Issue Information
Dear Colleagues,
The profound changes in electric energy generation and the strong requirements introduced by the rise in electric mobility are leading to previously unencountered challenges in areas such as energy storage, renewable energy source integration, the incorporation of innovative energy storage systems, and the design of fast-charging stations for battery electric vehicles. As a result, novel strategies and approaches must be explored.
Modular multilevel converters (MMCs) are a promising class of converter topologies that can perform multiple conversions concurrently, showing great redundancy and multiple degrees of freedom in their control structure. In the past 10 years, multiple solutions involving MMCs have been proposed, including spacing from motor drives, storage system integration, and photovoltaic (PV) system integration.
Researchers and experts in the field are encouraged to submit their original research contributions, survey papers, or tutorials for review in this Special Issue. The topics of interest include, but are not confined to, the following:
- New modular multilevel converters topologies;
- Storage integration by means of MMCs;
- Integration of PV systems with MMCs;
- Hydrogen generation using MMCs;
- Fast charging stations for electric vehicles based on MMCs;
- Modulation techniques;
- Control techniques for converter balancing;
- Innovative motor drives.

Title: Fault Tolerant Vector Space Decomposition Control for a Six-Phase PMSM Fed by a 5-Level CHB Converter
Authors: Mona Shayeghan; Marco di Benedetto; Alessandro Lidozzi; Luca Solero

Abstract: The growing demand for higher reliability and efficiency in modern electric drives, coupled with the increasing adoption of multiphase machines, has necessitated advancements in fault-tolerant control strategies. This paper presents a fault tolerance analysis for a six-phase permanent magnet synchronous machine (PMSM) connected to a five-level cascaded H-bridge converter, employing a level-shift pulse-width modulation (LSPWM) technique. To achieve fault tolerance, the system integrates three key strategies. First, a fault detection mechanism identifies faults in both machine phases and inverter legs. Second, an open-circuit fault compensation strategy modifies the inverter's faulty phase leg into a two-level inverter, minimizing additional losses and preserving healthy switches. Finally, a modified closed-loop control method is implemented to compensate for short-circuit faults. The proposed strategies are validated through simulations in Simulink and Hardware-in-the-Loop (HIL) testing, demonstrating improved system efficiency and robustness.
