Abstract
Apparatus for charging an electrical energy store from an AC voltage source. The apparatus includes a rectifier device with a capacitor interconnected in parallel with the rectifier device A current controller device is interconnected with the rectifier device. A converter device is interconnected with the current controller device. The converter device includes at least one first half-bridge having two switches connected in series, An inductor is interconnected with a connection point of the switches of the first half-bridge Depending on the voltage of the AC voltage source and a current through the inductor a switch of the current controller device and one of the switches of the first half-bridge of the converter device are switchable by means of a controller in such a manner that a current for charging the electrical energy store drawn from the AC voltage source and a voltage of the AC voltage source are substantially in phase.
