Advanced Technologies to Revolutionize EV Traction Inverter Design
Chipset solutions elevate performance and efficiency to new heights
As the electric vehicle (EV) market continues to accelerate, the traction inverter has become a critical component in the electric powertrain. Not only does it enable improved torque and acceleration in the electric motor, but it also plays a crucial role in regenerative braking, which requires careful consideration of thermal management and efficiency to ensure optimal performance. Designing a traction inverter that meets the stringent demands of tomorrow’s EVs requires careful consideration of functional safety, weight and power density, efficiency and thermal management, and software complexity.
To address these design challenges, Infineon offers a complete system solution that enables high-performance and safe traction-inverter systems with enhanced reliability and low cost. Their differentiated MCUs, power devices (SiC MOSFETs, Si IGBTs, GaN HEMTs), safety PMICs, current and positional sensors, gate driver ICs, and memory work together to provide a reliable and efficient traction inverter system that meets the demands of EVs.
