Abstract

There is described an asymmetric electronic half-bridge converter (10a). The electronic converter includes a positive input terminal (102a) and a negative input terminal (102b) for receiving a DC voltage (Vin), and two output terminals (104a, 104b) for providing a regulated output voltage (Vout) or a regulated output current (iout). The electronic converter moreover includes a half-bridge (S<1>, S<2>), a transformer (T) and a rectification and filter circuit (C<RS>, D, L<o>, C<o>) . The half-bridge (S<1>, S<2>) includes a first (S<1>) and a second (S<2>) electronic switch, connected in series between the two input terminals (102a, 102b), wherein a respective capacitance (C<A1>, C<A2>) and a respective diode (D<A1>, D<A2>) are associated with the first (S<1>) and the second (S<2>) electronic switch. A first terminal of the primary winding (T1) is connected to the intermediate point between the first (S<1>) and the second (S<2>) electronic switch, and a second terminal of the primary winding (T1) is connected via a first capacitor (C<RP>) to the positive (102a) or negative (102b) input terminal. The rectification and filter circuit (C<RS>, D, L<o>, C<o>) is connected between the secondary winding (T2) and the output terminals (104a, 104b). Specifically, the electronic converter includes a snubber circuit (30) on the primary side of the electronic converter (10a), wherein the snubber circuit (30) includes a second capacitor (C<S>), an inductor (L<S>), a first diode (D<1>) and a second diode (D<2>).
