An electronic converter comprising an input comprising two terminals for receiving a first power signal, and an output comprising two terminals for providing a second power signal. On the primary side, the converter comprises a half-bridge, a transformer and a first capacitor. Specifically, the first capacitor and the primary winding of the transformer are connected in series between the intermediate point of the half-bridge and an input terminal. On the secondary side, the converter comprises a diode, a second capacitor and an inductor. The second capacitor and the secondary winding of the transformer are connected in series between the cathode and anode of the diode, and the inductor and the output are connected in series between the cathode and the anode of the diode. The electronic converter comprises a third capacitor and at least one electronic switch adapted to selectively connect the third capacitor in parallel with the second capacitor.
