Switched Reluctance Motors (SRMs) have gained considerable attention in recent years, especially in the automotive industry (vehicle electrification), due to its advantages regarding cost, power density, simple construction, high efficiency, and high reliability. The SRM drives are the key components to ensure the proper, efficient, and safe operation of the SRMs. Due to the advantages of the 800V system EVs (compared to the current low-voltage 400V systems), such as higher efficiency, lower weight, lower volume, and faster charging time, there have been significant efforts by manufacturers such as Porsche and Audi to push toward higher voltage systems. The conventional SRM topologies such as asymmetric bridge inverters are two-level topologies, which would face higher voltage stress with the increase of the system voltage. This can lead to higher power loss, weight and cost. As such, multilevel inverters have been considered as an attractive solution for higher voltage applications due to their advantages such as low device stress, lower power loss, and higher power quality. The main focus of this project is on multilevel inverters for switched reluctance motor drives with the subprojects titled "New modulation and control techniques for DC-link capacitor minimization", "busbar design and packaging", "advanced gate driver for IGBTs". This will benefit Enedym Inc. in terms of developing low-cost, high-performance multilevel SRM drives that can eventually lead to wider adoption of EVs in Canada.

开关磁阻电机（SRM）近年来因其在成本、功率密度、结构简单、高效率和高可靠性方面的优势而受到广泛关注，特别是在汽车行业（汽车电气化）。 SRM驱动器是确保SRM正确、高效、安全运行的关键部件。由于800V系统电动汽车（与目前的低压400V系统相比）具有效率更高、重量更轻、体积更小、充电时间更快等优势，保时捷和奥迪等制造商一直在努力推动更高电压系统的发展。传统的SRM拓扑（例如非对称桥式逆变器）是两电平拓扑，随着系统电压的升高，其将面临更高的电压应力。这会导致更高的功率损耗、重量和成本。因此，多电平逆变器因其器件应力低、功率损耗低和电能质量高等优点而被认为是高压应用的有吸引力的解决方案。该项目的主要重点是用于开关磁阻电机驱动的多电平逆变器，子项目名为“直流母线电容器最小化的新调制和控制技术”、“母线设计和封装”、“IGBT 的先进栅极驱动器”。这将使 Enedym Inc. 受益于开发低成本、高性能的多级 SRM 驱动器，最终可以在加拿大更广泛地采用电动汽车。
