EMI Filters

Reduce EMI noise and meet stringent automotive standards

EMI Filters

High Power EMI Filters for EV applications avoid noise generated by EVs (electric drives and SMPS) spreading around the vehicle.

The high dV/dt and di/dt generated by switched mode power supplies - such as Drive Inverters, DC/DC, OBC - generate high frequency noise that could interfere with the sensitive electronics that control an electric vehicle. Schaffner HVDC filters are fully customized and engineered for every specific application, so achieving great filtering performance with a compact size.
