Abstract

The present invention is directed to a coupled inductor output filter to be used with DC/DC switched mode power supply topologies. This new output filter changes the inherent power sharing capability of most DC/DC converter topologies, enabling the overall converter to operate as a truly modular block with no inter-module communication required to accomplish power/current sharing on a multi-module configuration. The coupled-inductor output filter uses a split inductor, Lout1 and Lout2, a main output capacitor, Cout, and a DC blocking capacitor, CDC Block.
