Abstract
Simulacijom osnovnog sklopa su odabrane najpovoljnije vrijednosti za otpornike. Izlazna struja linearno ovisi o položaju potenciometra R2 na slici 1. Prva nadogradnja sklopa je ograničavanje maksimalne struje. To je postignuto tako da je dodan još jedan potenciometar čije su dvije priključnice kratko spojene u sekundarnoj grani. U sljedećoj nadogradnji dioda u sekundarnoj grani je zamijenjena zelenom svjetlećom diodom koja signalizira ispravan rad sklopa. Nakon toga dodana je nova grana koja je paralelna s izvorima napajanja a sadrži otpornik i crvenu LED. Ta grana služi za indikaciju neispravnog rada sklopa. Još je dodana i sklopka prije ulaza u naponski regulator A1. Simulacijom nadograđenoga sklopa se ne uočavaju nikakvi problemi, međutim kada se je sklop stavio na eksperimentalnu pločicu, javili su se neki problemi. Napon napajanja je trebalo značajno povećati zbog zelene LED jer je ona tražila pad napona od 12V. Mjerenje je pokazalo da je maksimalna izlazna struja nešto manja od 2A, a to je zbog velikih tolerancija otpornika od 0,62Ω.
Abstract (english)
Selection of best values for resistors is done by simulating basic scheme. Output current linearly depends on the position of the potentiometer R2 in Figure 1. The first upgrade is limiting the maximum current. This is achived by adding a potentiometer whose two terminals are short-circuited in the secondary branch. The following upgrade is diode in the secondary branch is replaces by a green light emitting diode, which signals the correct operation of the device. After that, another brach is added parallel to te power sources and contains a resistor and a red LED. This branch is used to indicate a incorrect operation of a device. By simulating the upgraded device, no problem shows up, but when it is put on a protoboard, there is several problems.
