Abstract
A transformer includes a magnetic core having multiple limbs. The transformer also includes a direct current (DC) bias winding wound around a specified one of the limbs. The transformer further includes a DC amplifier electrically connected to the DC bias winding. The DC amplifier is configured to receive a first signal associated with a load output current or voltage. The DC amplifier is also configured to determine an amount of a current for the DC bias winding based on the first signal. The DC amplifier is further configured to send the determined amount of current through the DC bias winding.
