BI-DIRECTIONAL DC-DC CONVERTER SYSTEM FOR FUEL CELL OUTPUT POWER CONVERSION

V diplomskem delu je predstavljeno načrtovanje, delovanje in izdelava dvosmernega pretvornika, ki s pomočjo regulacije skrbi za konstantno napetost na izhodu ne glede na obremenitev. Na začetku je predstavljeno delovanje pretvornika, statična karakteristika ter izpeljava modela s pomočjo matematičnih enačb. V nadaljevanju je predstavljeno načrtovanje sistema za vodenje ter regulatorjev v programskem okolju Matlab/Simulink. Delo vsebuje tudi načrtovanje tiskanine za realizacijo projekta. Na koncu pa so predstavljeni še rezultati meritev na realnem procesu.This thesis presents the development, operation and realization of bi-directional converter, which holds output voltage constant regardless of the load, using the control system. In the first section the operation of inverter and its static characteristic are presented, which are described by the model. Furthermore the design of the control system for and design of regulators in Matlab/Simulink environment are presented. Also included are design of PCB for the realization of the project. At the end of this work, there are presented the results of measurements on a real process
