Schaffner DC reactors

DC reactors

Smooth the current pulses in DC circuits

The primary purpose of a DC reactor is to smooth the current pulses in DC circuits and to reduce the damaging harmonics on the power line.

Schaffner DC reactors, also called DC link reactors or DC chokes, are typically connected to the semiconductors on the DC bus of converters, inverters and variable frequency drives (VFD).
