20.500.12556/DKUM-41975 NAPAJALNIK SVETIL LED LED LIGHTS POWER SUPPLY UNIT Namen Diplomskega dela je bilo izdelati napajalnik svetil LED. Predstavljene so teoretične podlage delovanja napajalnika, njegova izdelava, ter opravljene določene meritve. Napajalnik deluje na principu stikalnega usmernika, ki izmenično napetost pri visoki frekvenci pretvarja v enosmerno. Uporabili smo pretvornik navzdol, ker je želena izhodna napetost nižja od vhodne. Prednosti stikalnega napajalnika so boljši izkoristek vezja, vezje je manjše in posledično tudi lažje. The aim of the diploma work was to construct a power supply module for led lights. The operation of the module is presented in detail as well as its construction and assessment measurements. The module is based on the principle of switching power supply, which converts the alternating voltage waveform into DC voltage. The module is designed in a way that the output voltage is lower than the input voltage. The advantages of the switching power supply stems from better efficiency of the circuit, reduced size and reduced weigh. diode LED pretvornik DC-DC LM3444 stikalni napajalnik LED light DC-DC convertor LM3444 switching power true true false [A.
