Abstract
Vodik danas ima skroman udio u kombinaciji izvora energije u svijetu i EU-u te se i dalje uvelike proizvodi iz fosilnih goriva, ponajviše iz prirodnog plina i ugljena. Čisti vodik, proizveden elektrolizom i korištenjem obnovljivih izvora energije, može pridonijeti dekarbonizaciji teške industrije i cestovnog prijevoza tereta, u kojima se troše velike količine fosilnih goriva. Sustav fotonaponski panel-elektrolizer poboljšava se uvođenjem istosmjernog višerezonantnog pretvarača. U disertaciji je prikazan sustavni postupak projektiranja visokofrekvencijskog istosmjernog višerezonantnog pretvarača kao izvora konstantne struje optimiziranog za povezivanje elektrolizera s izvorom istosmjernog napona. Prikazana je analiza višerezonantnog pretvarača u uvjetima velikog signala u ustaljenom stanju za sve načine rada. U svim načinima rada pretvarač je opisan sustavima diferencijalnih jednadžbi čija su rješenja određena numerički gdje su za određivanje prijelaza između stanja i početnih uvjeta korištene trajektorije dvodimenzionalne ravnine stanja. Ravnina stanja je primijenjena i za sintezu dinamičkog modela pretvarača u uvjetima malog signala diskretnim modeliranjem u okolini radne točke. Primjenom diskretnog modeliranja u prostoru stanja dobivene su prijenosne funkcije višerezonantnog pretvarača u uvjetima malog signala u okolini radne točke ustaljenog stanja za sve načine rada. Temeljem dobivenih prijenosnih funkcija modeliran je digitalni PI regulator koristeći Matlab Sisotool.
Abstract (english)
Nowadays, hydrogen has a modest share in the combined energy sources both in the world and in the EU and it is still largely produced from fossil fuels, primarily from natural gas and coal. Pure hydrogen, produced by electrolysis using renewable energy sources, can contribute to the decarbonisation of heavy industry and road freight transport, both of which consume large amounts of fossil fuel. The photovoltaic panel-electrolyser system is improved with the insertion of a DC multi-resonant converter. The dissertation presents a systematic procedure of designing a high-frequency DC multiresonant converter as a constant current source optimized for connecting an electrolyser to a DC voltage source. The large signal analysis of a multiresonant converter in the steady state for all operating modes is presented. The converter is described with a system of differential equations whose solutions are numerically determined where the trajectories of two-dimensional state planes are used to determine the transitions and initial conditions in all modes of operation. The state plane was also used for the synthesis of the dynamic converter model in small signal conditions by discrete modelling near the operating point. By applying a discrete state space model, transfer functions of a multiresonant converter under conditions of a small signal around the operating point in the steady state for all operating modes are obtained. Based on the obtained transfer functions, a digital PI regulator is modelled using Matlab Sisotool.
