Abstract:
A system for charging a high voltage battery includes a low DC voltage battery, a DC-to-AC converting circuit, a controller, an AC-to-DC converting circuit and a high DC voltage battery. The low voltage battery outputs a low DC voltage signal. The DC-to-AC converting circuit receives the low DC voltage signal to convert into a chopped DC voltage signal. The DC-to-AC converter outputs a high AC voltage signal corresponding to the chopped DC voltage signal. The controller controls a duty cycle of the chopped DC voltage signal. The AC-to-DC converting circuit converts the high AC voltage signal into a high DC voltage signal. The high voltage battery charges using the high DC voltage signal. A method for charging a high voltage battery is also provided.
