Thesis (MScEng)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The versatility of power electronic converters has made them a dominant force in the current
electrical and electronic engineering industry. So too industry presents a wider range of
applications, forever demanding operation at higher power levels. To meet this need a variety
of multilevel converters have evolved. The challenge often lies in the selection of the appropriate
topology for a specific application. This thesis presents a practical comparison between
the Series-Stacked and Neutral Point Clamped multilevel converter topologies as candidates
for Medium Voltage Direct Current and Traction applications. Their configurations, characteristics,
switching techniques and practical performances are compared, in order to aid the
topology selection process. / AFRIKAANSE OPSOMMING: As gevolg van die veelsydigheid van drywings elektroniese omsetters word dit geimplementeer
in n toenemende hoeveelheid toepassings met toenemende drywings vlakke in die
elektriese en elektroniese industrie. Om aan hierdie behoefte te voorsien het n reeks veelvlak
omsetters ontstaan. Die uitdaging hiermee is die keuse van die toepaslike topologie vir n spesifieke
doelwit. Hierdie proefskrif vergelyk die Serie Gekoppelde en die Geklemde Neutrale
Punt omsetters ten opsigte van konfigirasie, karakteristieke, skakel tegnieke en praktiese
werksverrigting om die toepaslikheid te bepaal vir Medium Spanning Gelykstroom en Traksie
toepassings.
