Dual isolated input single power supply topology

摘要

An electric power supply system includes a transformer having two primary windings for receiving input power and a secondary winding for delivering output power, in which the primary windings are galvanically isolated from each other. A method for supplying electrical power to a load includes magnetically coupling a first primary voltage to a secondary power output; and magnetically coupling a second primary voltage to the secondary power output so that the second primary voltage is kept galvanically isolated from the first primary voltage.
