1. A power converter for use in a host vehicle, the power converter comprising:
a DC link;
a DC link capacitor; and
a pre-charge circuit configured to charge the DC link capacitor,
wherein the pre-charge circuit comprises a boost converter comprising a switch and inductor coupling terminals configured to couple to an inductive component external to the power converter, and
wherein the DC link is configured to receive a voltage from a first voltage source external to the power converter and the switch is operative to couple the inductive component to, and to decouple the inductive component from, a second, direct current, voltage source to provide a charging current to charge the DC link capacitor.
