Abstract: In at least one embodiment, a charging apparatus for a vehicle is provided. The apparatus includes a power converter having a primary stage, a first secondary stage, and a second secondary stage. The primary stage is configured to receive an incoming voltage to generate a first input voltage. The first secondary stage includes a first plurality of electrical components configured to generate a first portion of an output voltage. The second secondary stage is in series with the first secondary stage and includes a second plurality of electrical components configured to generate a second portion of the output voltage. Each of the first plurality of electrical components and the second plurality of electrical components is rated to a voltage rating that is less than a total sum of the first portion and the second portion of the output voltage.

Abstract: An on-board charger (OBC) for charging a traction battery of an electric vehicle includes a Power Factor Correction (PFC) stage to convert AC power from a mains supply into DC power for use in charging the traction battery, a bi-directional DC/DC converter coupled to the traction battery, a DC link capacitor between the PFC stage and the DC/DC converter, and a controller. The controller is operable to control the PFC stage and the DC/DC converter to operate in (i) a pre-charge mode in which the DC link capacitor is pre-charged using electrical power from the traction battery and (ii) a stable operation mode in which the traction battery is charged using the AC power from the mains supply.
