Abstract
Fokus ovog diplomskog rada je na odabiru optimalnih parametara pasivnih elemenata baterijskog pretvarača. Pod pasivne elemente spadaju prigušnice i kondenzatori u sustavu baterijskog pretvarača. Analiza započinje opisom rada PWM usmjerivača i baterijskog DC/DC pretvarača. Opisan je način upravljanja usmjerivača, njegove primjene, struktura, PWM modulacija te upravljanje tokom energije. Za silazno-uzlazni istosmjerni pretvarač obrazložena je njegova struktura, princip rada te je objašnjena razlika u radu pretvarača kada operira u uzlaznom ili silaznom modu. Proračuni veličina i analiza vladanja sustava baterijskog pretvarača izvršeni su u programu MATLAB, sa dodatkom programskog paketa PLECS verzije 3.6.9. Simulacije kojima se dolazi do potrebnih informacija za odabir parametara pasivnih elemenata pretvarača napravljene su u modelima realiziranim u PLECS-u. U trećem poglavlju rada, ovi modeli su detaljno opisani i obrazložen je način na koji se njima simuliraju realni uvjeti rada pretvarača. Na poslijetku, u četvrtom poglavlju, analiziraju se podatci dobiveni simulacijskim modelima iz trećeg poglavlja. Analiza započinje proučavanjem strujnih prilika u LCL filteru. Obrazložen je proces kojim se dolazi do odabira optimalnih parametara filtera koji garantiraju zadovoljavanje propisanih normi i pravilnika. Nakon toga analiziraju se veličine istosmjernog međukruga te se proučava kakav utjecaj na stabilnost DC linka imaju druge varijable sustava. Za kraj, proučavaju se pulzacije struje na niskonaponskoj strani silazno-uzlaznog istosmjernog pretvarača. Simulacijama se proučava potrebna vrijednost induktiviteta prigušnice u niskonaponskom krugu baterija koja osigurava dozvoljene pulzacije i kvalitetnu opskrbu energije baterijskom sklopu.
Abstract (english)
The focus of this thesis is in defining the optimal parameters of passive components in a battery converter. Inductors and capacitors in the system are regarded as passive components. The analysis begins by explaining the operating principles of PWM converters and buck-boost DC/DC converters. The methods of controlling PWM converters, it's applications, structure, PWM modulation and power flow control. The structure, applications and the difference between operating modes is explained for buck-boost DC/DC converters. Calculation and analysis of the battery converter system is done in MATLAB, with the addition of program pack PLECS v. 3.6.9. Simulations realized in PLECS, provide the necessary information for defining the optimum parameters of inductors and capacitors in the battery converter system. In the third chapter of this thesis, these simulating models are explained in detail. In the last chapter, information obtained from simulations is used to define the optimal parameterization of passive components in the battery converter. Parameterization begins with analysing the current pulsations in the LCL filter. The proces of defining the optimal parameters of the filter that will ensure meeting the norms is explained. After that, the DC link between two converts of the system is analyzed and variables that affect the stability of it are defined. In the end, current pulsations on the low voltage side of the DC/DC converter are analysed. With the help of simulations, the optimal inductance of this circuit is defined and the proper charging current is ensured.
