ABSTRACT:
A power supply and method of operation thereof. In one embodiment, the power supply includes: (1) a primary side power switch, (2) an isolation transformer having a primary winding coupled to the primary side power switch, the primary side power switch conducting intermittently to transfer current from an input of the power supply to the isolation transformer, (3) a secondary side power switch, coupled to a secondary winding of the isolation transformer, that is operable to conduct within a conduction period of the primary side power switch to transfer current from the isolation transformer to an output of the power supply, a portion of the current being contained within the power supply during a nonconduction period of the secondary side power switch and (4) a capacitor, coupled to the secondary side power switch, that, circulates the portion toward the output during the nonconduction period.
