Active electric filters Switched capacitor circuits Electric current converters Dissertations -- Electrical engineering Theses -- Electrical engineering Electrical and Electronic Engineering Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005. A switching state substitution must be developed that will make use of both single-phase redundancies and three-phase redundancies in the flying-capacitor topology. Losses should be taken into consideration and the algorithm must be designed for implementation on the existing PEC33 system, with on-board DSP (TMS320VC33) and FPGA (EP1K50QC208). The specific power-electronics application is a medium-voltage active filter. Existing capacitor voltage stabilisation schemes are investigated and a capacitor-voltage based algorithm is developed that is investigated in parallel with the Donzel and Bornard algorithm. Detailed simulation models are built for the evaluation of both existing and the proposed algorithm. Three-phase control is also evaluated. Timing analysis of the proposed algorithm shows that a DSP-only implementation of the proposed capacitor-based solution is not feasible. Detail design of the digital controller hereof is implemented in VHDL. Finally, a four-cell controller is fitted into the FPGA. A scalable hardware sorting architecture is utilised. 2006-11-21T06:36:46Z 2010-06-01T08:32:42Z 2006-11-21T06:36:46Z 2010-06-01T08:32:42Z 2005-03 Thesis http://hdl.handle.net/10019.1/1762 en_ZA University of Stellenbosch 7433032 bytes application/pdf application/pdf Stellenbosch : University of Stellenbosch |
