Capacitor Switching in APFC Panels

18 August 2017

Capacitor switching is a critical task in APFC panels because of the high inrush current taken and voltage transients initiated by capacitors at the time of switching. The switching device should be able to withstand both inrush current and voltage transients, along with the ability to carry rated capacitor constantly.


Thermal design of APFC Panels

12 May 2017

The life of the power capacitors and other equipments in APFC panels depend very much on the operating temperature. In panels with detuned harmonic filter reactors and thyristor switches, the chances of elevated temperature are high, as these equipments generate relatively more heat.
