An inductor is formed by two traces on a multilayer PC board passing through a ferromagnetic "E" shaped core. The first trace is the positive output bus of the DC power supply, and the second trace is the negative output bus of the DC power supply. Sense lines used to sense voltage levels in the load are put through the same opening in the ferromagnetic "E" core as an output bus trace. The sense lines are traces in a level of the multilevel PC board.
