Abstract:
Intenzivnost vpadne sončne svetlobe in temperatura sončnih celic imata velik vpliv na izhodno napetost. Tako se izhodna napetost sončnih celic spreminja predvsem v odvisnosti od osvetlitve, ob tem pa obstaja kompleksna povezava med sončnim vzbujanjem, temperaturo in totalno upornostjo polprevodniških celic. Iz omenjenega razloga imajo sončne celice nelinearen potek izhodnega izkoristka. S sledenjem točke največje izhodne moči na karakteristiki sočnih celic lahko zagotovimo optimalno izrabo pretvorjene sončne energije. V polnilnih sistemih je lahko izhodna napetost sočnih celic posledično prenizka za izvajanje polnilnega cikla, kar vključuje potrebo po dodatnem reguliranem pretvorniku enosmernih napetosti. Predmet raziskovanja v okviru predlaganega diplomskega dela je preučiti delovanje sončnih celic in razvoj polnilnega regulatorja za samodejno optimalno polnjenje akumulatorjev pri različnih pogojih sončne aktivnosti.

Title:
CHARGE CONTROLLER WITH MAXIMUM POWER POINT TRACKING OF SOLAR CELLS
Abstract:
The intensity of the entering sun light and the temperature of solar cells have a great impact on the cell output voltage. Thus the output voltage of solar cells change primarily because of different lighting conditions, where there is a complex connection between the Sun arousal, the temperature and the total resistance of solar cells. For the reason mentioned before, the solar cells have a non linear function of efficiency. By tracking the point of the highest output power on the output characteristic of the solar cells, we can ensure the optimal use of the transformed Sun energy. In the charging systems, the output voltage of the solar cells can be consequently too low to perform the charge cycle in which case there is a need for an additional regulating transformer of DC voltages. The main goal of this diploma paper is to investigate the activity of the solar cells and the development of the charging regulator for automatic optimum charging of batteries under different conditions of the Sun activity.
