Abstract
A synchronized switch tapped coupled inductor circuit which couples a first closed-loop regulated output of a forward converter switching power supply to a second output to assist in regulating the voltage of the second output. The switched power supply includes a converter transformer which is implemented as a forward converter providing the multiple outputs. The second output includes a storage inductor which is coupled to a storage inductor of the first output. The second coupled inductor includes a center tap which is connected to a synchronized switch. The synchronized switch is further connected to the first output and coupled to the converter transformer to detect the forward and flyback portions of each cycle. During the flyback portion of each cycle, the switch is turned on coupling the center tap to the first output. During the forward portion of each cycle, the switch is turned off, isolating the outputs from each other.
