Abstract:
1. An AC/DC power module for a plug-in hybrid electric vehicle having an electric drive system and an electric power supply, the power module comprising: a plug connectable to an AC power source; a rectifier having a rectifier input connected to the plug for receiving an alternating current therethrough, the rectifier having a rectifier circuit changing alternating current to direct current, the rectifier having a rectifier output supplying a direct current; a bidirectional DC to DC converter having a first converter terminal operating at a first voltage and a second converter terminal operating at a second voltage that is different than the first voltage, the bidirectional DC to DC converter having a converter circuit changing direct current to or from the first voltage and the second voltage, the first converter terminal connected to the rectifier output; an inductor, the rectifier comprising the inductor when during operation in a plug-in charging mode and the bidirectional DC to DC converter comprising the inductor during operation in a boost function mode and a buck function mode; a battery connected to the first converter terminal and the second converter terminal; and a bus connected to the first converter terminal and the second converter terminal, the bus connectable to the electric drive system.
