Abstract:Razsmernik, zasnovan na 2 pretvornikih navzgor je tip električnega pretvornika, ki ga lahko uporabimo v fotonapetostnih sistemih zaradi številnih prednosti kot sta minimalno število elementov in čista sinusna napetost brez potrebe po dodatnem filtriranju. Razsmernik pretvarja enosmerno napetost v izmenično, za dobro delovanje in stabilno izhodno napetost pa je potreben regulator, saj nanjo vpliva tako vhodna napetost kot tudi obremenitev. V diplomskem delu je predstavljeno načrtovanje regulatorja, programiranje DSP procesorja - AD pretvorniki in diskretni regulator ter načrtovanje in izdelava vezja za senzor izhodnega toka. Na koncu so podani rezultati testiranja in primerjava med krmiljenjem in regulacijo pri istih pogojih.

Title:CONTROL OF SINGLE-PHASE TWO-HALF BRIDGE BOOST INVERTER
Abstract:Inverter, based on 2 boost-converters, is a power converter, which is suitable for use in photovoltaic systems, mainly because of minimum number of circuit components and output voltage, which has clear sinusoidal waveform, so there is no need for additional filtering. Inverter converts DC voltage into AC voltage, which is dependent of input voltage variations and load changes, so to get a stable output, we need to implement closed-loop control. This diploma includes compensator design, DSP programming - AD converters and a discrete compensator, and output current sensor circuit design. At the end, test results for open and closed-loop control are presented, so they can be easily compared.
Keywords:single-phase inverter, cascade control, feedforward, PI compensator, lag-lead compensator, DSP, AD converter, Altium Designer
