Traction inverters for 400 V and increasingly 800 V battery platforms must convert DC battery energy into efficient three-phase AC motor drive, switching hundreds of amps at high frequency while minimizing losses, managing heat, and maintaining galvanic isolation between the high voltage power stage and low voltage control electronics.
Vishay's silicon carbide MOSFETs, power modules, and IGBTs deliver the low on-resistance and fast switching needed for peak efficiency, while Automotive Grade optocouplers provide isolation voltages up to several kilovolts. Our DC-Link film capacitors with low ESR and high ripple current capability keep the power stage stable and reliable, and our Power Metal Strip® shunt resistors add the precise, low drift current sensing traction control systems can rely on.
Behind high voltage traction inverter efficiency and reliability is The DNA of tech.®
