Abstract

This thesis concerns the design and construction of a closed-loop controlled matrix converter induction motor drive, using transputer parallel processors. The modulation algorithms used for the matrix converter are described. A 2.5 kW experimental matrix converter using IGBT switching devices has been constructed and tested. An analysis of the losses in the converter has been carried out and this gives good agreement with the measured losses.

Two modulation algorithms, the Venturini algorithm and the scalar algorithm have been implemented in real-time on a network of parallel transputer processors. Experimental results are presented to compare the operation of these two algorithms. Open-loop constant V/F control of the matrix converter induction motor drive has been demonstrated. A controller has been designed to achieve closed-loop speed control of the drive system, employing the slip regulation technique. The experimental results under various operating conditions have verified the correct operation of both control systems. The indirect vector control technique has also been implemented. The results demonstrate the steady-state and transient performance as well as the regenerative operation of the drive system. The application of a matrix converter to a high performance induction motor servo drive rated at 2.5 kW with true four quadrant capability and minimum passive components has been demonstrated.
