MOBILITY SOLUTIONS

Wide bandgap semiconductors (SiC and GaN), known for their high voltage capability, thermal robustness, and high frequency performance, are reshaping power electronics in electric mobility.
Their primary applications include traction inverters and energy systems. SiC power modules in traction inverters greatly reduce switching and conduction losses, improving overall conversion efficiency. This enhances drivetrain performance, reduces system size and weight, and can extend EV driving range by approximately 10%.
In charging systems, SiC devices enable the construction of 800V high voltage fast-charging platforms. Both onboard chargers (OBCs) and DC fast charging stations benefit from higher switching frequencies, lower thermal stress, and increased power density. They significantly improve charging speed, enabling ultra-fast charging equivalent to 200 km of range in 5 minutes.
By elevating energy efficiency and charging performance, wide bandgap semiconductors are addressing key EV challenges and accelerating the transition towards full vehicle electrification.
