Abstract

The interfacing between the various electrical engineering fields is not emphasized in the electrical engineering laboratory; the traditional aim of a laboratory course is to complement a single theoretical course. The object of this thesis is to provide means, hardware and software, that can be used in different system configurations to perform useful industrial tasks. The chosen task is to control electrical machines using a microcomputer. Experiments can be written to be performed by students, using these systems. The emphasize of these experiments can be on the characteristics of a power electronics device, but the device will be seen as part of a system; or the emphasis can be on the microcontroller and its programming. but the program will be tested by examining the behavior of the machine it is supposed to control; or the emphasis can be on the characteristics of an electrical machine and then the rest of the system provides the required voltages and currents.

Power electronics modules, using SCRs and MOSFETs. and a microcomputer module designed around the 8052AH-BASIC microcontroller, are built. Various programs are written. Systems can be easily built using some of those modules and programs to control a DC machine or an induction motor using different methods of control.
