Abstract
Sustav napajanja bespilotne letjelice može se optimirati dodavanjem sunčanih ćelija kao dodatnim izvorom energije na letjelici. Inačice bespilotne letjelice s dodatnim fotonaponskim napajanjem i bez njega su međusobno uspoređene. Dobiveni su rezultati koji pokazuju da je za isto vrijeme leta potrošeno manje naboja iz baterije kad je letjelica imala ugrađene sunčane ćelije. Za povećanje djelotvornosti dodanih sunčanih ćelija, izrađen je uzlazni pretvarač upravljan mikrokontrolerom koji služi za podizanje napona sunčanih ćelija kod smanjenog sunčevog zračenja. Mikrokontroler upravlja uzlaznim pretvaračem prema metodi napona praznog hoda za određivanje točke maksimalne snage sunčanih ćelija. Bespilotne letjelice mogu se koristiti za sve složenije namjene u praksi ako se optimiranjem sustava napajanja produlji njihovo vrijeme leta.
Abstract (english)
The power supply of pilotless plane can be optimized by the addition of solar cells as an additional source of energy on the plane. Different versions of one pilotless plane with added photovoltaic power supply and without it are mutually compared. The obtained results show that for the same flight time it spends less charge form the battery when the plane has solar cells on. To increase the effectiveness of added solar cells, it has been made an boost converter controlled by microcontroller, which serves to raise the voltage of solar cells during the reduced solar radiation. The microcontroller controls the boost converter according to the method of open circuit voltage to determine the maximum power point of solar cells. Pilotless planes can be used for more complex applications in practice if their flight time is extend by the power supply optimization.
