Abstract
U ovom radu izvršena je analiza rada silazno-uzlaznog pretvarača tijekom punjenja i pražnjenja litij-ionskih baterija. Za vrijeme punjenja baterija pretvarač radi u silaznom a za vrijeme pražnjenja u uzlaznom režimu rada. Upravljački sustav pretvarača sastoji se od jednostavnog regulacijskog kruga struje baterije s PI regulatorom i PWM modulatorom, a prelazak iz režima punjenja i pražnjenja baterija realizira se promjenom predznaka reference struje baterijskog niza. U programskom paketu MATLAB/Plecs izrađen je simulacijski model pretvarača sa serijskim spojem litij-ionskih baterija na niskonaponskoj strani, te konstantnim naponom na visokonaponskoj strani pretvarača. Simulirani su odabrani stacionarni i dinamički režimi rada punjenja i pražnjenja litij ionskih baterija, a analizom dobivenih rezultati potvrđena je valjanost simulacijskog modela.
Abstract (english)
The operation of the buck-boost converter during charging and discharging of lithium-ion batteries is analyzed in this undergraduate work. During battery charging the converter operates in buck mode and during discharging in boost mode. The converter control system consists of a simple battery current control loop with PI controller and PWM modulator. The transition from battery charging and discharging mode is realized by changing the sign of the battery current reference. Simulation model of the converter with a serial connection of lithium-ion batteries on the low-voltage side and a constant voltage on the high-voltage side was developed in the MATLAB / Plecs software package. Selected stationary and dynamic modes of charging and discharging of lithium ion batteries were simulated, and the validity of the simulation model was confirmed by the analysis of the obtained results.
