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.
EliteSiC Power Modules for Traction Inverter
onsemi utilizes decades of R&D of SiC technology to create a revolutionary wide bandgap product family. The EliteSiC power modules for traction inverters offer bare die solutions, gel-encapsulated case modules, and transfer molded modules, all incorporating full SiC MOSFETs. Compared to IGBT solutions, the EliteSiC product family offers increased performance, better efficiency, and higher power density in similar and highly compatible packaging solutions.
Ve-Trac Family
The VE-Trac power modules, available with IGBT silicon, are the components that convert direct current (DC) battery power in electric vehicles (EVs) or hybrid electric vehicles (HEV). EVs and HEVs have a lithium-ion battery which is now the leading e-battery technology that stores the energy in DC cells, our product then extracts that energy and converts it into alternating current to drive the electric motor. This power source is what creates propulsion for the car. The technology encompasses everything from range and performance to battery life and how the car feels when you are behind the wheel.
