Abstract: A method of controlling a rectifier includes receiving a gain factor, receiving a ramp interval, and generating a rectifier switch control voltage. The rectifier switch control voltage is an over-modulated rectifier switch control voltage generated by a pulse width modulator using the gain factor. The amount of over-modulation in the rectifier switch control voltage is decreased during the ramp interval for reducing transient voltage overshoot events at the start of active rectification.

Abstract: A power converter includes a first set of transistors electrically connected in series, a second set of transistors electrically connected in series, and an AC link. The second set of transistors is electrically connected in parallel with the first set of transistors to form an H-bridge. The AC link is electrically connected between the first and second sets of transistors. A plurality of H-bridges are connected in parallel and a three-wire DC bus is electrically connected to the H-bridges.

Abstract: A bobbin for spacing windings around an inductor core includes an interior spacer defining an exterior surface for coupling interior spacer with an annular inductor core and an interior facing surface opposing the exterior surface for receiving inductor windings. The interior spacer has a thickness profile between the exterior and interior facing surfaces for spacing the windings inward from the inductor core to reduce magnetic fringe flux effects on the windings. An inductor body includes an inductor core coupled to bobbin. A wound inductor includes windings wrapped around the inductor body formed by the inductor core and bobbin.
