Explore power electronics enabling EV acceleration from 0 to 100 in 3 seconds. Find solution guide with development advice and power semiconductor recommendations, focusing on traction inverters.
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.

SiC Modules contain SiC MOSFETs and SiC diodes. The boost modules are used in the DC-DC stages of solar inverters. These modules use SiC MOSFETs and SiC diodes with voltage ratings of 1200V.
A Silicon Carbide (SiC) Module is a power module that operates with Silicon Carbide semiconductors for its switch. The purpose of a SiC power module is the transformation of electrical power through switches to improve system efficiency.
The primary function of SiC Modules is to transform electrical power. Silicon Carbide offers an advantage over silicon because, with less resistance to move away from the source (due to increased efficiency), SiC devices can operate at a higher switching frequency. A SiC based system is also more compact and lightweight than a silicon solution, allowing for smaller designs. Therefore, SiC devices are the ideal solution for situations where you want to increase efficiency and improve your thermal management.
The VE−Trac™ is a line of power modules designed for xEV traction inverters, available in 6-pack and H-bridge configurations. Pick IGBT, Si or EliteSiC MOSFET module technology.
Reliability is as critical as power density in traction inverters. Leverage a mature, more robust planar technology base to deliver a performance comparable with trench.
