Abstract: An asymmetric electronic half-bridge converter includes a positive input terminal and a negative input terminal for receiving a DC voltage, and two output terminals for providing a regulated output voltage or a regulated output current. The electronic converter moreover includes a half-bridge, a transformer and a rectification and filter circuit. The half-bridge includes a first and second electronic switch, connected in series between the two input terminals, wherein a respective capacitance and a respective diode are associated with the first and second electronic switch. A first terminal of the primary winding is connected to the intermediate point between the first and second electronic switch, and a second terminal of the primary winding is connected via a first capacitor to the positive or negative input terminal. The rectification and filter circuit is connected between the secondary winding and the output terminals.
