Abstract
An apparatus and method for testing a battery charger includes a converter having input terminals connectable to a battery charger for receiving a current, output terminals and a switching device for electrically connecting at least one of the input terminals to the output terminals. A load is connected to the output terminals. A controller controls the switching device to periodically connect the input terminals to the output terminals, and in a preferred embodiment, maintain a desired voltage across the input terminals.
