At least one embodiment of the invention aims to provide a way of avoiding undesired and/or impermissible voltage and/or frequency increases in the alternating-current isolated network. For this purpose, the drive system includes according to the invention an energy absorbing device arranged in the intermediate circuit, which energy absorbing device includes at least one energy absorber, which preferably includes at least one electrical resistor, for absorbing at least a part of the electrical energy that the three-phase drive machine generates in generator operation and outputs to the intermediate circuit by way of the motor-side current converter of the converter. The energy absorber can be activated by the energy absorbing device according to the polarity of the intermediate circuit voltage. The energy absorbing device is preferably variable regarding an absorption of electrical braking power of the three-phase drive machine.

    Abstract: Two inverters in series in the DC line of a slip-recovery motor drive of the SCR controlled type are asymmetrically controlled to allow reduced current reflected back in the transformer. Two secondaries in the transformer are associated with the respective inverters. Reduced rating of the transformer, reduced saturable reactor in the DC link and improved power factor are direct advantages of such arrangement.

    Abstract: A switched resonant power converter applies AC to an induction motor. The power converter controls the magnitude and phase of the motor current, and tuning the stator flux accordingly in order to control the motor speed. A preprocessor operates on a speed command signal by getting the user speed command input to produce amplitude and phase-related signals for application to inputs of the power converter control.
