Mitsubishi Electric Corporation has announced a new free service, launching June 28, that will provide design and validation data for its proprietary prototype inverter used in power conversion systems (PCSs). The move is aimed at helping customers speed up development cycles for renewable energy applications, particularly in solar.
The prototype inverter is built around Mitsubishi Electric’s latest 8th-generation insulated gate bipolar transistor (IGBT) modules. With this release, the company is opening up detailed design insights and performance data that would otherwise take significant time and resources for customers to generate independently.
The service will cover three-level inverter designs and include experimental data developed in collaboration with Taiwan’s Industrial Technology Research Institute (ITRI).
It also provides comprehensive reference data for Mitsubishi Electric’s Industrial LV100-type 1.2kV IGBT modules, designed for large-capacity PCSs, as well as NX-type 1.2kV modules suited for medium- to large-scale systems.
By making this data accessible, Mitsubishi Electric is targeting some of the most time-intensive parts of inverter development component selection, thermal and layout design, manufacturing, and system-level validation ultimately reducing engineering workloads and shortening time to market.
As renewable energy deployment accelerates globally, demand for high-performance PCSs continues to rise. Large-scale installations such as utility-scale solar plants increasingly rely on megawatt-class, high-voltage systems, where three-level inverter architectures are essential for improving efficiency while maintaining compact designs.
However, integrating power semiconductors at this level remains complex, with challenges spanning thermal management, fault protection, high-density layouts, and extensive validation requirements. Mitsubishi Electric’s new service directly addresses these bottlenecks.
