Minimization of DC link capacitance in transportation application

The DC-link capacitor is a bulky and expensive component. Therefore, there is an interest in reducing its capacitance in order to reduce both cost and size. An appropriate converter control can lead to a reduction of this component. In this thesis, the state of the art regarding capacitor reduction...

Descrição
Resumo:The DC-link capacitor is a bulky and expensive component. Therefore, there is an interest in reducing its capacitance in order to reduce both cost and size. An appropriate converter control can lead to a reduction of this component. In this thesis, the state of the art regarding capacitor reduction in the DC-link is analysed and classi ed according to the type of method employed. A general simulation is presented and analysed including all the components that conform the power electronics stage of a real scheme for vehicle hybridization. Using that scheme, some reduction methods are carried out and compared with the base case
