First Claim
1. A charging apparatus for a vehicle, the apparatus comprising:
- a power converter including;
a primary stage configured to receive an incoming voltage to generate a first input voltage;
a first secondary stage including a first plurality of electrical components configured to generate a first portion of an output voltage for charging at least one battery in a vehicle in response to the first input voltage; and
a second secondary stage in series with the first secondary stage including a second plurality of electrical components configured to generate a second portion of the output voltage in response to the first input voltage,wherein 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
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.
