Power Electronics Capacitor

Power electronics capacitors can be used for a wide variety of applications, even where extremely non¿¿¿sinusoidal voltages and pulsed currents are present. Both AC and DC capacitors are available. AC capacitors are periodically recharged during operation; DC capacitors are periodically charged and discharged without recharge.

Applications and uses

· Filters

· GTO and IGBT snubbers

· Smoothing

· Commutation

· Medium frequency applications

· Induction heating processes

Capacitor types

  • AC/DC capacitors for general use
  • Axial low inductance AC/DC capacitors
  • Radial low inductance AC/DC capacitors
  • GTO Snubber axial low inductance capacitors
  • PK¿¿¿16 low inductance DC capacitors
  • SR17TM DC capacitors for traction
  • DC capacitors for general use
  • 3¿¿¿phase AC filter capacitors
