Method for operating a charge device for a voltage drop compensation device and device for carrying out the method

The charging voltages (U(LA),U(LB),U(LC)) are generated in response to a drive signal, such that the charging currents (I(LA),I(LB),I(LC)) injected in the corresponding phases (A,B,C) is proportional to a phase system voltages (U(NA),U(NB),U(NC)) of corresponding phases (A,B,C) of an electric AC voltage supply system (4). An Independent claim is also included for charger operating apparatus.
