Abstract
A power-factor correction arrangement incorporates an active inductance source and a passive capacitance source switchably connected in parallel across a source of AC power. The active and passive sources are directly interconnected at their switched ends by a resistance, the value of which is chosen so that, when the passive source is switched into circuit while the active source is already connected to the AC source, the current through the passive source suffers virtually no surge.
