Abstract
A rapid charging device for a battery includes a filtering stage of resistive-inductive-capacitive type to be connected to a three-phase network, a buck stage, a boost stage to be connected to the battery, an induction winding interposed between the buck stage and the boost stage, and a regulating unit capable of imposing chopping duty cycles on the buck stage and on the boost stage. The regulating unit compensates the phase shift induced by the filtering stage between the currents and the voltages taken from each phase of the three-phase network and also maintains the value of the current amplitude passing through the winding above a non-zero predefined threshold.
