Abstract
A power converter includes an energy transfer element, a switched element, a secondary control circuit, a primary switching, and a primary control circuit. The secondary control circuit generates a voltage pulse across a secondary winding of the energy transfer element while the secondary winding provides current to an output. The secondary control circuit is coupled to vary a voltage across the switched element to generate the voltage pulse across the secondary winding in response to an output of the power converter. The primary control circuit is coupled to the primary switch and a third winding of the energy transfer element. The primary control circuit is coupled to switch the primary switch to regulate the output in response to the voltage pulse. The secondary winding is coupled to reflect the voltage pulse onto the third winding which is on the same side of the energy transfer element as a primary winding.
