Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005. / This thesis discuss an investigation into the applicability of modern high frequency power
conversion technology in the plasma mineral processing industry. The physics governing
the plasma in a processing environment are analysed to provide a clear understanding
of this plasma as electrical load. This was done to create an electrical model for the
plasma as load and gain understanding into the electrical supply requirements. Modern
high frequency power conversion technology is contrasted with thyristor controlled line
frequency technologies to provide a suitable starting point for the study. A 3 kW soft
switched converter is proposed for application with a plasma load. This converter is
designed and verified. The small-signal signature of the proposed converter under peak
current mode control is investigated and a new model is proposed to describe this control
configuration.
