Thesis (Masters Diploma (Electrical Engineering)--Cape Technikon, Cape Town,1991 / A detailed study into the development of a three phase motor drive, inverter and microprocessor controller using a scalar control method. No mathematical modelling of the system was done as the drive was built around available technology. The inverter circuit is of a Vo~tage source inverter configuration whicp uses MOSFETs switching at a base frequency of between 1.2 KHz and 2 KHz. Provision has been made for speed control and dynamic braking for special applications, since the drive is not going to be put into a specific application as yet, it was felt that only a basic control should be implemented and space should be left for special requests from prospective customers. The pulses for the inverter are generated from the HEF 4752 I.e. under the control of the micro processor thus giving the processor full control over the inverter and allowing it to change almost any parameter at any time. Although the report might seem to cover a lot of unimportant ground it is imperative that the reader is supplied with the back-ground information in order to understand where A.e. drives failed in the past and where A.e. drives are heading in the future. As well as where this drive seeks to use available technology to the best advantage.

M.Ing. (Electrical and Electronic Engineering) / This thesis covers the development of the Mosmatrix, a high speed, high power switch which is implemented with an array of mosfet switching elements. The switching performance of the Mosmatrix proves that is is possible to employ existing semiconductor technology to switch pulses of 1,5 Joule, several hundred Ampere at several kilovolt, in the microsecond and sub-microsecond regime. The switch has demonstrated rates of current rise in the order of lOkA per J.1s during tumon without the use of tum-on snubbers (magnetic assist) . The rate of current fall during tum-off has been of the same magnitude. No other switch has demonstrated this level of repetitive current interrupt ability. The work covers the properties, switching requirements anc' switching performance of mosfet switching elements as well as the development of an isolated drive circuit.
