Abstract

This paper describes the design and construction of a scale model asynchronous motor drive including pulse width modulated (PWM) rectifier for traction system training purposes. The control systems are implemented in software using a digital signal processing (DSP) system based on the TMS320C31 microprocessor. The DSP system offers the ability to display system waveforms and interactively change system parameters on the IBM PC. 1. Introduction The Drives Power Electronics and Traction Systems Laboratory at the University of Central Queensland is currently conducting a programme of continuing education for Queensland Rail engineering and technical staff, [1]. The work mainly focuses on the
