DRIVING A SYNCHRONOUS DC-DC TRANSMITTER WITH ANALOGUE PROCESSOR COMPARATOR

V diplomskem delu so predstavljeni DC-DC pretvorniki in njihova zgradba ter pomen. Podrobneje smo predstavili sinhroni navzdol/navzgor pretvornik v delovanju navzgor. Opisana je tokovna regulacija takšnega pretvorniškega sistema uporabo analognega komparatorja na procesorju TMS320F28379D. Pretvornik in njegovo vodenje smo najprej modelirali v simulacijskem programskem orodju in ga simulirali. V programskem okolju Altium Designer smo načrtali pretvornik, tokovno regulacijo pa v programskem okolju Code Composer Studio. Izdelali smo tudi dejanski pretvornik in na njem izvedli poizkuse ter za vodenje uporabili digitalni signalni krmilnik.In this thesis are presented DC-DC converters, their structure and importance. We have presented synchronous buck-boost converter in the boost operation and its control with analog comparator processor TMS320F28379D. There is also described the current control of this converter system. For the control of DC-DC converters, we used digital signal controller. We have modelled the converter and its control in simulation programing tool and simulated it. We also tested the control on the prototype of the converter
