Abstrakt
Paljud on küll kuulnud ülikondensaatorist ja selle headest omadustest millest olulisemateks võiks lugeda kiiret laadimist ning väga suurt laadimis- tühjenemistsüklite arvu, kuid ülikoolis tudengina pole olnud võimalust ülikondensaatorit näha või katsetada. Selle bakalaureusetöö eesmärgiks ongi valmistada katsestend kus tudengid saavad laboratoorses töös kokku panna katsestendi vastavalt skeemile, ning seejärel katsestendiga teostada mõõtmisi millest järeldada kuidas käitub ülikondensaator laadimisel ja tühjenemisel.
Töö teoreetilises osas antakse ülevaade energiasalvestitest ja nende põhiparameetritest, ning kirjeldatakse ülikondensaatori ehitust, omadusi ja kasutusvaldkondi. Töö praktiline osa hõlmab endas katsestendi skeemi valmistamist programmiga Circuit wizard ning skeemi põhjal valmistati reaalne ülikondensaatori katsestend. Viimases osas on lõputöö autori poolt koostatud laboratoorne töö, mille vajalikud mõõtmised teostatakse ülikondensaatori katsestendiga. Katsestendiga on võimalik mõõta kuidas pinge muutub ülikondensaatori täitumisel ning on võimalik jälgida pinge muutumist ka ülikondensaatori tühjenemisel.
Many have heard of the supercapacitor and its good properties. One of the most important properties are fast charging and very large of charge-discharge cycles, but as student in university it has not been possible to see or test the supercapacitor. The aim of this bachelor’s thesis is to prepare a test bench, where students can assemble a test bench in the laboratory according to the scheme, and then perform measurements with the test bench to see how the supercapacitor behaves during charging and discharging. The theoretical part of the work gives an overview of energy storages and their basic parameters, and describes the construction, properties and applications of the supercapacitor. The practical part of the work involves the to build test bench scheme with the program Circuit wizard, and on the basis of the scheme to build a supercapacitor test bench. In the last part, the author of the dissertation has prepared a laboratory work, the necessary measurements of which are performed with a supercapacitor test bench. With the test bench it is possible to measure how the supercapacitor voltage changes on charging and monitor how voltage decrease while discharging.
