12 Conclusion

The automotive traction inverter is trending towards 800-V technology, high-power density (towards larger than 50 kW/L), high efficiency (> 99%), and high safety (ASILD) requirements. TI technology and devices, such as MCUs, isolated gate drivers, isolated bias supplies, safety PMICs, active discharge, position sensing, isolated voltage, and current sensing help enable high-performance and safe traction-inverter systems with enhanced reliability and low cost.
