USE OF MICROCONTROLLER TMS320F28069 INTHE POWER ELECTRONICS SYSTEMS CONTROL

V diplomskem delu je predstavljena izvedba tokovnega modulatorja-regulatorja z uporabo mikrokrmilnika TMS320F28069 podjetja Texas Instruments. Podan je opis DC/DC-pretvornika navzgor. Opisano je delovanje tokovne modulacije-regulacije, njene slabosti, ter opis napetostne regulacije. Podan je opis digitalnega signalnega krmilnika in uporabljenih perifernih enot. Podrobneje je predstavljeno delovanje primerjalnika. Prav tako so opisane značilnosti koprocesorske enote (CLA), njena inicializacija, nastavitve pomnilnika, komunikacija med koprocesorsko enoto in CPE ter omejitve za programiranje v programskem jeziku C. Opisana je izvedba programske opreme in njeno delovanje ter predstavljena programska oprema, ki se izvaja na CPE, in programska oprema, ki se izvaja na CLA. Na koncu so prikazani še simulacijski in eksperimentalni rezultati.The diploma thesis presents the implementation of a current mode controller using the microcontroller TMS320F28069 produced by Texas Instruments. It provides a description of the DC/DC boost converter. Moreover, it describes the functioning of current mode control, its disadvantages and the feedback control. It also provides a description of a digital signal controller and applied peripherals. The functioning of the comparator is described in further detail. Furthermore, the thesis provides a description of characteristics of the co-processing unit (CLA), its initialization, memory settings, communication between the co-processing unit and the CPE as well as the limitations on programming in the C language. In addition, it describes the implementation of software and its functioningit also introduces the software implemented in the CPE and the software implemented in the CLA. In the end, it presents the simulation and experimental results
