    Abstract: A resonant-mode power supply, comprising an assembly of switches connected in a bridge or a half-bridge configuration, a series resonant circuit connected in the bridge or half bridge diagonal, a part of which is formed by a multi-winding inductor by means of which a load is connected, and a controller configured to stabilize output voltages or currents by controlling the switching frequency of the assembly of switches. The series resonant circuit comprises an energy recirculation circuit (ERC1) for limiting the resonant circuit quality factor, connected through the diode rectifier (DR2) to the supply voltage node and a current monitoring circuit (CMC) configured to monitor the recirculation circuit current (Ilim) and, by means of the controller (C), to change the switching frequency of the assembly of switches (K1, K2, K3, K4) in order to reduce power supplied to the resonant circuit upon exceeding the threshold value by the current (Ilim) in the energy recirculation circuit (ERC1).
