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.
Vishay’s NTC thermistors and temperature sensors help monitor and protect critical inverter components, while our power and film resistors support functions such as precharge, discharge, and snubber circuits. Together, these technologies support the thermal management, protection, and control functions required for reliable traction inverter operation.
