High-power, high-performance automotive SiC traction inverter reference design


Design files


TIDM-2014 is a 800-V, 300kW SiC-based traction inverter system reference design developed by Texas Instruments and Wolfspeed provides a foundation for OEMs and design engineers to create high-performance, high-efficiency traction inverter systems and get to market faster. This solution demonstrates how the traction inverter system technology from TI and Wolfspeed improves system efficiency by reducing the overshoot in available voltages with a high-performance isolated gate driver and real-time variable gate drive strength driving the Wolfspeed SiC power module. The isolated gate driver coupled with TI’s isolated bias supply solution significantly reduces the PCB size providing more than 2X smaller PCB area, less than 4mm height and eliminating 30+ discrete components improving system power density. TI’s high-control performance MCUs featuring tightly-integrated, innovative real-time peripherals enable effective traction motor control even at speeds greater than 20,000 RPM. Fast current loop implementation helps minimize motor torque ripple and provides smooth speed-torque profiles. The mechanical and thermal design of the system is provided by Wolfspeed.

  • Real-time variable gate drive strength features enable improvement in system efficiency by minimizing the SiC switching power losses and accurate bias supply minimizes conductive losses.
  • Isolated gate drivers and bias supply module reduce PCB area by 30%.
  • High performance MCUs enable industry’s fastest motor control loop (<2 µs), which helps to minimize torque ripple and provides smooth speed and torque current profiles to the traction motor.
  • UCC5880-Q1 and AM2634-Q1 are Functional Safety-Compliant targeted devices.
  • Enhance system reliability with reinforced rated capacitive isolation technology and early failure detection.
