A power module includes a packaging structure having a pair of side-by-side spaced apart busbars, each connected to a corresponding switch. The power module includes a conductive pad, between and electrically isolated from the busbars and the switches, and configured to, responsive to flow of current through the busbars generated by the switches and resulting in power loop magnetic flux between the busbars, generate magnetic flux that partially cancels the power loop magnetic flux.
