Abstract
A positive current feedforward compensator for a PFC converter is proposed and demonstrated. This compensator is applied to a converter with a boost topology operating in continuous conduction mode with average current control. The compensator adjusts the current reference in order to counteract the effects of the time-varying source impedance. Experimental measurements verify that the compensator improves the stability of a converter that is connected to a source with a time-varying impedance.
