摘要

The drive (2) has an intermediate voltage circuit converter (4) and an electric motor (6) which is attached at the terminals with the outputs (R,S,T) of a load-side pulse power converter (8) of the intermediate voltage circuit converter. A converter output-side measuring current (18) is provided with a signal input (20) of signal electronics (10) of the pulse power converter. Each output is connected in an electrically conducting manner with a bus bar (DCP,DCN) of an intermediate voltage circuit (28) of the converter by a low-pass filter (22,24,26). An independent claim is included for a method for correcting the voltage failure of a load-side pulse power converter.
