A power control arrangement for a vehicle includes a bi-directional DC/DC converter and one or more controllers. The one or more controllers, after a request to activate the vehicle, command the bi-directional DC/DC converter to charge a DC link capacitor electrically between main contactors and the bi-directional DC/DC converter to a target value without connecting a resistor in parallel with one of the main contactors and before closing all of the main contactors.
