Abstract
A rectifier for a switching power supply or the like. The recitifier has a plurality of diodes coupled in parallel, each diode having in series therewith a saturable inductor and a node disposed between the diode and the inductor to form a diode/inductor pair. At least one resistor is connected between at least two of the nodes to assure nearly equal current flow in the diodes. Alternatively, a link winding on at least two of the inductors are coupled together to achieve current balancing.
