Abstract

The transient and steady state performance of a group-triggered cycloconverter supplying a controlled slip induction motor is studied using an analog computer. System equations are derived from equivalent circuits for the cycloconverter, source, and motor networks. The induction motor is represented in terms of qdo components in a stationary reference frame. Computer results are compared with test data on a laboratory system for both motoring and dynamic braking modes of operation. Commutation failures in the power circuit are illustrated and discussed. Good agreement between computer output and laboratory tests suggests the method of analysis can be used for optimizing circuit design and improving overall system operation.
