Abstract
A power converter circuit includes a transformer. The transformer includes a primary winding and a secondary winding. The power converter circuit uses energy conveyed from the primary winding of the transformer through the secondary winding of the transformer to produce an output voltage to power a load. Control circuitry of the power converter circuit initiates conveying a portion of the received energy through the secondary winding back through the primary winding to control a magnitude of the output voltage. For example, if the magnitude of the output voltage is above a desired setpoint value, such as due to a transient load condition or change in the setpoint of the output voltage, the control circuitry reduces the magnitude of the output voltage by conveying excess energy from an output capacitor (that stores the output voltage) through the secondary winding to the primary winding.
