DC-DC CONVERTER FOR THERMOELECTRIC SYSTEM

V diplomskem delu so predstavljeni termoelektrični elementi, njihova zgradba in osnovno fizikalno ozadje delovanja. Opisana je zgradba laboratorijskega sistema za preizkušanje termoelektričnih elementov. Za slednjega so predstavljeni merilni rezultati in karakteristika. Vključen je tudi opis pretvorniškega sistema, natančneje pretvornika navzgor. Glede na izmerjeno karakteristiko sistema je bila zasnovana osnovna regulacija pretvornika. Na podlagi rezultatov je bilo potrjeno delovanje pretvornika in regulacije na takšnem sistemu. Predstavljene so tudi osnovne ugotovitve in zaključki o delovanju sistema za preizkušanje termoelektričnih elementov.Thermoelectric elements, their construction and basic physical background of operation are presented in the thesis. The work describes the design of a laboratory prototype for thermoelectric element testing, measurements and characteristics of the system. Also included is a basic description of the converter system, specifically boost converter. A basic control algorithm was designed, with respect to the measurements and characteristics of the system. Operation of the boost converter and the control algorithm was confirmed, based on the output measurements. Also included are the basic findings and conclusions regarding the operation of the laboratory prototype for thermoelectric element testing
