ABSTRACT:
The present invention relates to a bidirectional flyback switch mode power supply (SMPS), such as a bidirectional flyback converter, and a method for operating it. The SMPS comprises a transformer having primary and secondary windings inductively coupled together, said primary winding being coupled to a voltage input of the converter and said secondary winding being coupled to a voltage output of the converter; a primary control unit comprising a primary switch arranged in series with the primary winding and a secondary control unit comprising a secondary switch arranged in series with the secondary winding. The primary control unit is adapted to compensate input voltage variations, and the secondary control unit is adapted to provide a controlled output power on the secondary side.
