Abstract
U ovom diplomskom radu opisana je didaktičko-multimedijalna oprema Lucas Nuelle, koja se u laboratoriju koristi u svrhu odrađivanja vježbi iz energetske elektronike. Oprema proizvođača Lucas Nuelle se sastoji od sučelja UniTrain-I sa pripadajućim eksperimentatorima, seta eksperimentalnih kartica i računalnog programa LabSoft. U programu LabSoft objašnjeno je kako dobiti valne oblike struje i napona istosmjernog pretvarača. Nakon opisane opreme, opisana je analiza rada istosmjernog pretvarača. Istosmjerni pretvarač se može nalaziti u dva režima rada: kontinuiranom i diskontinuiranom. Jednokvadrantni silazni pretvarač se nalazi u kontinuiranom režimu rada ako struja kroz zavojnicu ne padne na nulu tokom periode. Ako struja kroz zavojnicu tokom periode padne na nulu, silazni pretvarač se nalazi u diskontinuiranom režimu rada. U kojem režimu rada se nalazi jednokvadrantni silazni pretvarač ovisi o odnosu između vremenske konstante d i sklopne periode Ts. U prvom djelu vježbe se MOSFET nalazio u gornjoj vodljivoj grani. Prikazani su preko vremenskog dijagrama valni oblici struje i napona trošila, preko osciloskopa valni oblici napona zavojnice i napona otpornika, te preko digitalnog osciloskopa naponi na ventilima. Vježba se ponovila u drugom djelu, kada se MOSFET nalazio u donjoj vodljivoj grani.
Abstract (english)
In this graduate thesis are described a didactic and multimedia equipment Lucas Nuelle, which is used in laboratory for the purpose of doing practice in the field of energy electronics. Equipment of the manufacturer Lucas Nuelle is made of UniTrain-I interface with the belonging experimenters, a set of experimental cards and a LabSoft computer program. In the LabSoft computer program it is explained how to produce wave shaped current and voltage of the DC converter. After described equipment, the analysis of DC converter and buck converter is described. The buck converter can operate in two modes: continuous and discontinuous. A buck converter operates in continuous mode if the current through the inductor never falls to zero during the period. If the current through the inductor falls zo zero during the period, the buck converter operates in discontinuous mode. In which mode buck convertor will operate depends of the relation between time constant and switching period. In the first part of the exercise the MOSFET was in the high side of the scheme.The waveforms of current consumer and voltage consumer are shown through the time diagram, the waveforms of voltage inductor and waveform of voltage resistor are shown through osciloscope. The waveforms of voltage through MOSFETs are shown by digital osciloscope. The exercise was repeated in the second part when MOSFET was in the low side of the scheme.
