Rapid reswitching of induction machine from current source inverter on the supply net

The contribution deals with the dynamics of induction machine during reswitching process from the main feeder on the stand‐by one. The main feeder may be a current source inverter in which case the machine, before switching off, may be operated with lower frequency than the frequency of the stand‐by supply net. It causes that the electromotive force on the opened machine terminals is no longer a measure of the magnitude of the rotor currents. The analysis was carried out with recognition for the magnetic saturation of the main flux.
