Abstract (en)

[origin: EP0936845A1] The supply circuit has a resonant system (C1, C2, L1, L2) supplied by the output of a rectifier circuit (Vdd, GND). A switching device (SW) is connected in series with the resonant system. A first detector (12) opens the switch when the current exceeds a set level. A second detector (14) closes the switch at each zero crossing of the voltage at a node (N1) of the resonant circuit.
