Conclusion

EVs are driving technology innovations across the board, from processing to power semiconductors. Motor control and powertrain designs have a direct influence on EV ranges and driving performance. The combination of accurate current sensors and smart MCUs with real-time control are able to help reduce latency and improve the accuracy of the motor-control loop, enabling smooth speed and torque transitions. With reduced harmonics distortion, the electrical efficiency and range improve; so do motor vibrations, which help prevent an uncomfortable drive.

Traction inverter power density and efficiency enabled by the adoption of SiC MOSFETs and 800-V technology allow the integration of various powertrain functions and ultimately increased range per charge. TI’s wide portfolio of integrated semiconductor technologies enable flexibility for automakers and Tier-1 suppliers to achieve high performance and low cost.
