The presence of several electro-mechanical components and sub-assemblies in automotives is susceptible to emit EMI noise or be exposed to external sources of energy – resulting in unanticipated changes in system operation. This noise is classified into two categories – Broadband (due to electrical arcing) and Narrowband (due to active electronics). Original Equipment Manufacturers (OEM) address these EMC considerations in the component and system design phase to build immunity characteristics.
The increasing number of Electric Vehicles (EVs) on the roads brought about the need for more charging stations, including DC fast charging stations. With the increasing demand of the charging station installation, the impact of EMI becomes more critical as it can impact both charger and the Vehicle. The power conversion circuit in the EV application can produce high level of emission.
With the growing shift to EVs and PHEVs, and the accelerated incorporation of electronic components in automobiles, noise suppression has become increasingly important in order to ensure EMI compliance.
EMI filters have been adopted for use in various automotive applications, from ABS and ECU automotive power trains/safety equipment and other automotive devices. Our solutions address EMI challenges in power electronics, onboard chargers and battery operated vehicles.
