300 kW Three-Phase Traction Inverter

TIDM-02014 is an 800-V, 300 kW SiC-based traction inverter system reference design developed by Texas Instruments and Wolfspeed which provides a foundation for design engineers to create high performance, high-efficiency traction inverter systems and get to market faster. The design features automotive qualified SiC XM3 modules, high-performance isolated gate drivers with real-time variable gate drive strength, isolated bias supply with integrated transformer, along with TI’s real-time performance MCUs that enable traction motor control even at speeds greater than 20,000 RPM while supporting functional safety requirements.

Detailed design documentation and test results are available from Texas Instruments reference design page.
