Traction Inverter

Main traction inverters are the heart of electric vehicles and provide incredible amounts of torque and acceleration. The responsiveness of the inverter and the electric motor it controls correlate directly to the “feel” of the vehicle and consumer satisfaction. 

Power levels from 40 kW to 250+ kW are common, and these systems require extremely robust IGBT and silicon carbide (SiC) components. Scalability enhanced thermal performance, and the industry’s lowest packaging inductance allow traction inverter designers to achieve peak efficiencies, state-of-the-art power density, and swift response times. 400 V to 800 V batteries supply power to traction inverters, requiring inverter components to be rated from 600 V to 1200 V while operating at current levels up to 1000 A per phase. EliteSiC and VE-Trac module solutions from onsemi provide the foundation for traction inverter design, making your automotive products powerful and reliable.
