Mitsubishi Electric Corporation has begun shipping low-current 3.3kV/400A and 3.3kV/200A versions of a Schottky barrier diode (SBD) embedded silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) module for large industrial equipment, including rolling stock and electric power systems, from today, June 10.

Together with the existing 3.3kV/800A version, the newly named UnifullTM series comprises three modules to meet the growing demand for inverters capable of increasing power output and power conversion efficiency in large industrial equipment. The new modules will be exhibited at major trade shows, including Power Conversion Intelligent Motion (PCIM) Europe 2024 in Nuremberg, Germany from June 11 to 13.

Mitsubishi Electric’s SBD-embedded SiC-MOSFET modules, including the 3.3kV/800A version released on March 29, feature an optimized package structure to reduce switching loss and improve SiC performance. Compared to existing power modules, UnifullTM┬ámodules, significantly reduce switching loss and contribute to higher power output and efficiency in large industrial equipment, making them suitable for auxiliary power supplies in railcars and drive systems with relatively small capacities.
