Integrating eighth generation power modules into industrial automation systems

Mitsubishi Electric Corporation is launching ten new models of its industrial-use NX-type 1.2kV insulated gate bipolar transistor (IGBT) modules to optimize power conversion efficiency in heavy machinery. The semiconductor devices are specifically engineered for deployment within inverters that control machine tools, industrial robots, and large-capacity motor drive systems.

Enhancing efficiency in digital infrastructure and robotics
Modern industrial automation demands power components that minimize thermal losses while handling increased current densities. To address this operational challenge, the new modules utilize eighth-generation IGBT technology. By optimizing the internal layout of both the IGBT and the diode, the design reduces power loss by up to approximately 19% compared to previous generations. This reduction directly lowers the overall power consumption of the host industrial equipment, enhancing system reliability and thermal management.

Technical architecture and standardized integration
The product rollout includes a new 1000A-rated model, which achieves a 1.25-fold increase in current rating over current models without expanding the physical footprint. Maintaining the standardized Industrial NX-type package dimensions allows engineering teams to integrate the components into existing digital infrastructure and inverter layouts. This backwards compatibility eliminates the need for mechanical chassis redesigns, thereby shortening the development cycle for new inverter platforms.

Implementation and public evaluation
Sample shipments for the ten models are scheduled to begin on a sequential basis starting June 15, 2026. Prior to deployment, Mitsubishi Electric Corporation will present the NX-type 1.2kV IGBT modules at the Power Conversion Intelligent Motion (PCIM) Expo & Conference 2026 in Nuremberg, Germany, from June 9 to 11, 2026. Additional technical demonstrations are planned for upcoming industrial exhibitions in Japan, China, and other international markets to verify performance parameters across diverse grid environments.
