Abstract
An electrical vehicle charging device includes a power converter for receiving an AC voltage from an AC grid or a DC voltage from a DC grid, a transformer having a primary side connected to an output side, a full wave rectifier having a first input and a secondary input and a positive output and a negative output, at least two output capacitors connected between respective end taps of end taps connected in series via a center tap and between the positive output and the negative output, whereby the end taps are for providing the DC voltage to the electrical vehicle, and a switch connected in series between the first input or the secondary input and the center tap, and whereby the electrical vehicle charging device is adapted for closing and/or opening the switch depending on a DC voltage level required for charging the electrical vehicle.
