20.500.12556/DKUM-20000 TOKOVNA REGULACIJA ENOSTOPENJSKEGA DC-AC PRETVORNIKA CURRENT MODE CONTROL OF SINGLE-STAGE DC-AC CONVERTER V diplomskem delu so predstavljeni razsmerniški sistemi, njihova zgradba in pomen. Podrobneje smo predstavili enostopenjski enofazni DC-AC pretvornik. Opisana je tokovna regulacija takšnega razsmerniškega sistema, s katero je mogoče pretvornik priklopiti na elektroenergetsko omrežje, pri tem pa energijo enosmernega vira na vhodu prenašati v omrežje. Pretvornik in tokovno regulacijo smo najprej načrtovali v simulacijskem programskem orodju,rezultati simulacij so podani. Izvedli smo tudi preizkuse na prototipu pretvornika, za katere so prav tako predstavljeni rezultati. Za vodenje pretvornika smo uporabili digitalni signalni procesor, za katerega smo napisali programsko kodo. Inverter systems, their structure and operation are presented in diploma thesis.Single-stage single-phase DC-AC converter is described in details. Current control of such an inverter system, which enables connection of such a converter to electrical power grid, is described. It makes possible the transfer of the DC power source energy to the AC grid. Converter and current control were first designed in the simulation software tool, the results of simulations are included. Experimental tests were performed on a prototype converter, for which the results are also presented. For the control of the converter a digital signal processor was used, for which a software code was written. enostopenjski razsmernik DC-DC pretvornik DC-AC pretvornik tokovni vir tokovna regulacija napetostna regulacija kaskadna regulacija P-regulator PI-regulator PD-regulator elektroenergetsko omrežje digitalni signalni procesor programska koda single-stage inverter DC-DC converter DC-AC converter current source current control voltage control cascaded control P-controller PI-controller PD-controller power grid digital signal processor program code true true false [L.
