1. A converter comprising:

  • a primary switch network coupled to a power source, wherein the primary switch network comprises a plurality of power switches;

    a controller configured to generate gate drive signals for the plurality of power switches;

    a secondary rectifier coupled to an output;

    a first transformer having a first winding coupled to the primary switch network, a second winding coupled to the secondary rectifier and a third winding coupled to the controller; and

    a second transformer having a fourth winding coupled to the primary switch network, a fifth winding coupled to the secondary rectifier and a sixth winding coupled to the controller, wherein a voltage signal from the third winding and/or the sixth winding is processed to provide a feedback of a voltage at the output.
