20.500.12556/DKUM-83287 Brezžični prenos energije z dvojnim DD navitjem doktorska disertacija The Wireless Power Transfer Using Double DD Coils V tej nalogi je predstavljen razvoj nove strukture oddajnih in sprejemnih navitij za brezžični prenos energije. Razvita nova struktura navitij je zasnovana na osnovi navitij z usmerjenim magnetnim pretokom. Navitja omogočajo prenos večje gostote moči na enaki površini, kot že znana navitja. Zaradi razlike v novi strukturi navitij je bilo potrebno prilagoditi tudi sam sistem za brezžični prenos energije. Predstavljeni sta dve strukturi pretvornikov za vzbujanje navitij, ki omogočata prenos večje gostote moči. Za potrebe regulacije sistema z novo strukturo navitij, je bil izdelan linearni, malo-signalni model sistema. Na podlagi simulacije s programom Matlab, so bili izdelani in preizkušeni različni regulatorji. Načrtana sta bila regulator izhodne napetosti in regulator izhodnega toka. Na koncu je bilo delovanje nove strukture navitij preverjeno tudi na eksperimentalnem sistemu za brezžični prenos energije manjše moči. Primerjali smo izkoristek sistemov in največjo preneseno moč. Preizkusili smo integracijo tokovne in napetostne regulacije. The thesis presents the development and implementation of the new wireless power transfer coil structure. The proposed coil structure is based on the well-known bipolar coil with the directional magnetic flux. The advantage of the new coil structure is higher power density on the same base coil area. Due to the change in the structure, the system for wireless power transfer also needs to be changed. As a solution, two different converters for driving the proposed coil structure are introduced. Together with the coil structure, the converter transfers higher power density. For the purpose of the control synthesis, a linear, small-signal model of the converter circuit was developed. The current and voltage controller were designed and tested using Matlab. The theory behind the new coil structure was tested using a small-scale, low-power wireless power transfer system. The tests included efficiency and output power comparison. Finally, the integration of the voltage and current control was tested. brezžični prenos energije induktivni prenos energije razvoj navitij DD navitja večja gostota prenosa moči napetostna in tokovna regulacija wireless power transfer inductive power transfer coil structure development DD coils increased power density voltage and current control true true false [N.
