Abstract:
Magnetically isolated feedback circuits and regulated power supplies are disclosed. In some embodiments, a magnetically isolated feedback circuit includes an isolated gate drive circuit and a forward converter circuit. The isolated gate drive circuit is operable to receive a plurality of pulses, wherein the isolated gate drive circuit produces a plurality of isolated bi-polar pulses from the plurality of pulses. The forward converter circuit is electrically coupled to the isolated gate drive circuit and is operable to be electrically coupled to a load. The plurality of isolated bi-polar pulses causes the forward converter circuit to sample a voltage at the load as a sampled voltage. The forward converter circuit is operable to provide the sampled voltage to a feedback input of a pulse width modulator.

Claim (Index 11):
A regulated power supply comprising:\n a pulse width modulator operable to produce a plurality of pulses at an output and receive a sampled voltage at a feedback input; a switching transistor comprising a gate electrically coupled to the output of the pulse width modulator; an output transformer comprising an output primary and an output secondary, wherein the output primary is operable to be electrically coupled to a voltage source and is electrically coupled to a drain of the switching transistor, and the output secondary is operable to be electrically coupled to a load; a magnetically isolated feedback circuit comprising:\n an isolated gate drive circuit electrically coupled to the output of the pulse width modulator, wherein the isolated gate drive circuit produces an plurality of magnetically isolated bi-polar pulses from the plurality of pulses directly from the output of the pulse width modulator; and \n a forward converter circuit electrically coupled to the isolated gate drive circuit for receiving the plurality of magnetically isolated bi-polar pulses, wherein:\n the forward converter circuit is operable to be electrically coupled to the load; \n the plurality of magnetically isolated bi-polar pulses causes the forward converter circuit to sample a voltage at the load as the sampled voltage; and \n the forward converter circuit is operable to provide the sampled voltage to the feedback input of the pulse width modulator, wherein the forward converter circuit is directly coupled to the pulse width modulator.
