TOKYO, June 5, 2026 – Mitsubishi Electric today has announced a new technical support service to speed the development of three-level inverters. This allows customers to access both design and validation data such as experimental results obtained in cooperation with Taiwan’s Industrial Technology Research Institute (ITRI).
The program targets two of Mitsubishi Electric’s flagship IGBT modules: the Industrial LV100-type 1.2kV module for large-capacity power conversion systems (PCSs) and the Industrial NX-type 1.2kV module for medium- to large-capacity applications. The two modules employ the company’s most recent eighth-generation IGBT technology. With detailed data available on these components, Mitsubishi Electric hopes to ease the burden on engineers working through parts selection, circuit design, manufacturing and system-level validation to ultimately help bring renewable energy inverters to market faster.
But building such systems is anything but trivial. The use of high power semiconductors in designs of the megawatt class presents a host of engineering challenges: thermal management becomes significantly more complex, fault protection schemes need to be carefully tuned, physical layout must strike a balance between high component density and electrical performance, and system level validation is an expensive and time-consuming endeavor.
That’s where Mitsubishi Electric’s new service comes in. Design documentation, including physical geometry, component placement and electrical schematics, will be provided to customers for prototype inverters based on the LV100 and NX modules. In addition, they will benefit from real-world validation data on thermal behaviour and short-circuit protection performance, two areas that have traditionally been major technical challenges in the development of medium to large-capacity systems.
