SIMULATION OF CHOPPER FED D. C. MOTOR DRIVE SYSTEM-PROBLEM ORIENTED APPROACH

ABSTRACT The purpose of this article is to develop an efficient simulation program for the steady state performance of a chopper fed separately excited D.C. motor drive system. The effectiveness of this method lies in the evaluation of the initial state vector of a state equation representing chopper-electromechanical system without passing through the transient region. Effects of source impedance, chopper circuit configuration/parameters have been discussed in detail to prove the generality of this simulation approach.
