Claim of US Patent No. 10,433,379

1. Apparatus for providing a direct current to a load, at first and second main outputs, the apparatus comprising:a synchronous rectifier operatively connectable to a secondary winding of a transformer whose primary winding is for carrying high-frequency alternating current; the synchronous rectifier having first and second outputs;
wherein the synchronous rectifier comprises first and second switches and a control circuit comprising:
a further secondary winding of the transformer, a control port configured to control the first and second switches of the synchronous rectifier and thereby to turn the synchronous rectifier on and off, and a subcircuitry configured to provide a voltage to the control port;
wherein the first and second rectifier outputs are directly connected to the first and second main outputs respectively:
wherein the subcircuitry is connected to the first and second main outputs.
