Abstract

V diplomskem delu so predstavljeni DC-DC pretvorniki, njihova zgradba in pomen. Podrobneje smo predstavili zaporni pretvornik. Opisana je napetostna regulacija takšnega pretvorniškega sistema, s katero je možno natančno nastaviti vrednost izhodne napetosti pretvornika ter pulzno gostotna modulacija, s katero želimo doseči višje stikalne frekvence kot pri pulzno širinski modulaciji. Pretvornik in napetostno regulacijo smo načrtovali v simulacijskem programskem orodju Matlab/Simulink. Izdelali smo tudi dejanski pretvornik in na njem izvedli poizkuse. Za vodenje pretvornika smo uporabili digitalni signalni krmilnik.

Secondary title: Closed loop control of the flyback converter with pulse density modulation
Secondary abstract: DC-DC converters are presented in the work, more precisely, their configuration and importance. In detail, flyback converter was presented. There is also described control of such converter system, with which is possible to precisely determine the output voltage value of the converter. Also pulse density modulation is presented, with which is possible to achieve higher switching frequency than with the pulse width modulation. Converter and the control were first designed in the simulation program tool Matlab/Simulink. Also an actual converter was build and experiments were performed on it. For the control of the converter digital signal controller was used.
