RP695 EMC/EMI Filters for EV Charging Stations

Electrifying EMI/EMC Solution with Compact Form Factor

RP695 EV Charging Station

Hackettstown, NJ – November 2022 - Astrodyne TDI, global developer, and manufacturer of power conversion and EMI/EMC solutions, introduced a new EMI/EMC Filter for EV charging stations to mitigate electromagnetic noise in the EV charger space. The RP695 EMI filters for EV Chargers feature a compact form factor that can fit tight spaces and are ideal for high voltage DC applications. These EMI/EMC filter solutions will help EV charging OEM achieve critical, expensive, and often time-consuming emissions compliance without a need for major changes to their already designed charger cabinet. This will reduce time to market for OEMs, which can accelerate the adoption of EV charging stations around the globe, facilitating the adoption of “green” electric vehicles.

These filters help in situations where a 3-phase filter alone at the point of power entry is not sufficient in achieving conducted and radiated compliance because the noise from the DC side (output) can couple back on the input side and/or radiate. Placing a properly designed DC filter at the EV Charger output can greatly mitigate these issues, helping faster emissions compliance.

Astrodyne TDI’s RP695 series is a high current dual-stage DC EMI/EMC solution that operates up to 1500 VDC. The design also features a hybrid extruded-molded design to minimize weight and cost. These features are especially important for high voltage DC EV Charger applications where space and weight are crucial. The RP695 filters are currently offered in 450 A, 600 A, 1000 A, and 1600A rated currents and selectable Y-capacitor values from 0 to 2000nF. To ensure peace of mind, Astrodyne TDI can provide a “no-charge” on-site pre-compliance testing to minimize the unexpected costs and time to market.

RP695 EMI/EMC filters are ideally suited for: 

  • DC fast chargers
  • High power rectifiers
  • Inverters
  • Induction and industrial chargers
  • Solar
