Abstract
In at least one embodiment, a vehicle battery charger is provided. The vehicle battery charger includes at least one transformer, a first modular converter, a filter, and at least one controller. The first modular converter includes a first plurality of switching devices to generate a first voltage signal in response to a filtered input signal. A second plurality of switching devices generate a second voltage signal. The filter is operably coupled to the first modular converter and provides the filtered input signal to the first modular converter in response to a first input signal from a mains supply. The filtered input signal includes a detectable current portion and an undetected current portion. The controller is programmed to determine the undetected current portion based at least on a capacitance of the filter and generate a first control variable to compensate for the undetected current portion.
