The invention provides an automotive variable voltage converter with an inductor having a hidden air gap. The automotive power converter includes a pair of series connected switches and an inductor including a core having a leg, a winding wound around the leg, and a terminal center tapping the switches. The leg includes a plurality of alternating frames and solid blocks arranged to define a continuous contact surface for the winding and to define internal cavities within the leg such that each of the frames surrounds one of the internal cavities.
