Beschreibung
Zusammenfassung:	An asymmetric half bridge flyback converter, comprising a first primary side switching device and a second primary side switching device coupled in series between a supply voltage and a reference potential, a transformer, wherein one end of a primary side winding of the transformer is coupled to a node between the first primary side switching device and the second primary side switching device, a capacitor, wherein a resonant circuit including at least the primary side winding and the capacitor is coupled in parallel to the second primary side switching device, and a controller controlling the switches devices. The second primary side switching device is configured to prevent or reduce current flow in both directions when switched off.
