DC link capacitors are used for balancing the variation of power between the different DC power rails in the system. These variations can occur in case of activity from eighter the input stage (pantograph or battery) or the output stage, motor and wheels.
It is a vital “Link” for stabilizing the ripple generated by the high frequency switching circuits in the traction inverter, typically an IGBT module.
Faratronic’s C3E series features several specifications that are beneficial for use in these typical high current, fast switching environment:
- Low Ls & ESR
- High rms current capability
- Self-healing property, segmented metalized film design
- Stainless steel case, epoxy resin sealing
- Dry construction, no leaking fluids.
