Abstract
An example device for simultaneous transfer of alternating current (AC) and directed current (DC) power includes a power converter or inverter circuit having a switch, a power magnetic device comprising a coupled winding, a DC power output loop for delivering DC power to a DC load, and an AC power output loop for delivering AC power to an AC load. The DC power can be a function of a direct current (DC) component of a current of the power inductor, and the AC power can be a function of an induced and/or switching alternating current (AC) ripple component of the current of the power inductor. In addition, the device can include a controller operably coupled to the power converter or inverter circuit. The controller can include a processing unit and a memory and can be configured to independently regulate the DC power and the AC power.
