Abstract
A method for operation of a compressor supplied by a power converter having an operating condition (B) for the compressor () supplied by a power converter, generated from a measured actual rotational speed (n) of the compressor and a given effective current component (i) of a measured power converter output current (I) using a stored speed-dependent pump characteristic curve (SG) monitored for validity such that on determining invalidity, as per a stored speed-dependent instantaneous curve, a control signal (S) for reducing a torque (M) is generated. A method for operation of a compressor supplied by a power converter is then achieved with which the duration and the intensity of surge conditions is significantly reduced.
