Abstract

The purpose of this work was to develop and test the switched capacitors-boost converter (SC-BC), which can be used for stepping up voltage by a factor of at least ten driving energy harvesting applications. Extensive mathematical modelling of SC-BC was done for obtaining its nonlinear model and equations of multiple static characteristics. Simulations of SC-BC and its simplified models were done within a PSIM environment. The choice was made for closed-loop to use the combination of a PI controller and sliding mode control due to the robustness requirements and excellent closed-loop dynamics. Control was implemented on digital signal processor TMS320F28335 within a MATLAB/SIMULINK environment. Lastly the open and closed-loop experiments were done on a real SC-BC prototype.

Secondary title:	PRETVORNIK NAVZGOR S PREKLOPNIMI KONDENZATORJI ZA TERMOELEKTRIČNI SISTEM
Secondary abstract:	Namen tega dela je bil razvoj in testiranje pretvornika navzgor s preklopnimi kondenzatorji (SC-BC), kateri je lahko uporabljen pri dvigovanju enosmerne napetosti za faktor vsaj deset, v aplikacijah za sisteme z zbiralniki energije. Za pretvornik je bilo napravljeno obširno matematično modeliranje, kjer smo pridobili njegov nelinearni model in enačbe večih statičnih karakteristik. Simulacije pretvornika so bile opravljene v programskem okolju PSIM. Za regulacijo v zaprti zanki je bila uporabljena kombinacija PI regulatorja in regulatorja drsnega režima, zaradi zahtev po robustnosti in dobri zaprto-zančni dinamiki. Regulacijski algoritem je bil implementiran s pomočjo digitalnega signalnega procesorja TMS320F28335 v programskem okolju MATLAB/SIMULINK. Nazadnje smo prav tako izvedli meritve realnega prototipa pretvornika v odprti in zaprti zanki.
