摘要
A process and a device are disclosed for operating as on-board charging set the inverse rectifier (4) of the threephase current drive (2) of an electric car. In the charging mode of operation two bridge arms (18, 22) of the inverse rectifier (4) are set as boos regulator, so that a direct voltage (Ud) is supplied to an intermediate capacitor (16) of the inverse rectifier (4) depending on a mains-friendly supply, whereas a further bridge arm (20) of the inverse rectifier (4) is set as a buck regulator, so that a charging current from the intermediate capacitor (16) is supplied to the driving battery (10) of the electric car depending on a charging characteristic thereof. By adding simple elements, the inverse rectifier (4) of the threephase current drive (2) of an electric car can thus be used as an on-board charging set, saving volume and weight in relation to known electric cars.
