Claim Text:
1. A power delivery device comprising: a DC/DC converter disposed between an input and an output; a primary-side controller configured to control an input current of the DC/DC converter; a secondary-side controller connected with AC coupling to the output, the secondary-side controller configured to feed back electric power information of the output to the primary-side controller; an insulation circuit connected to the secondary-side controller, the insulation circuit configured to feed back the electric power information of the output to the primary-side controller; and a DC/AC component separating circuit connected to the insulation circuit, the DC/AC component separating circuit configured to feed back the electric power information of the output to the primary-side controller, wherein the insulation circuit is an insulating bidirectional circuit connected with DC coupling to an output of the DC/DC converter, wherein the primary-side controller varies an output voltage value and an available output current capacity of the DC/DC converter by controlling the input current on the basis of the electric power information fed back from the secondary-side controller through the insulation circuit and the DC/AC component separating circuit.
