Comparison of Computer and Test Results of a Static AC Drive System

Abstract
The effectiveness of an analog computer (electronic differential analyzer) in studying the performance of a rectifier-inverter-induction motor drive system is demonstrated. Computer diagrams are not given. However, methods of simulating the system components sufficient to describe their dynamic and steady-state behavior are described and references cited. Computer recordings are compared with results obtained from a prototype of an actual drive system. In particular, computer and test results showing the six-phase rectifier output voltage, filter inductor current, filter capacitor voltage, inverter current, as well as the stator voltage and current of the induction motor are compared. The facility of the analog computer in predicting the behavior of a large involved drive system is demonstrated.
