DC-link capacitors

Design and construction

The intermediate circuit DC capacitors are available in a variety of designs such as, for example, with metallized film and double-sided metallized film capacitors, as dry non-inductive capacitors in a plastic or aluminium housing.

Features

  • Voltage range from 250 VDC up to 20’000 VDC
  • Capacitance range from 0,001 uF up to 6’000 uF
  • Capacitance tolerance ± 5%, ± 10% and ± 20%

Applications

For DC capacitors in intermediate circuits, there are a variety of applications such as GTO snubber circuits, frequency converters in wind turbines, solar inverters, solar and wind inverters, switching applications, filters etc.
