Abstract

U ovom radu prikazane su promjene na poboljšanoj laboratorijskoj maketi u odnosu na staru maketu, odnosno problemi koji su se javili na staroj maketi te rješenje tih problema na poboljšanoj maketi. Realiziran je sklop za mjerenje struje te su podešeni parametri rada (frekvencija rada, ulazni i izlazni napon, opseg promjene struje) za sva četiri prekidačka izvora napajanja kako bi se omogućilo što jednostavnije i preciznije mjerenje karakterističnih struja. Također, prikazan je izgled nove tiskane pločice te valni oblici karakterističnih struja svih četiri prekidačkih izvora napajanja koji su izmjereni na poboljšanoj laboratorijskoj maketi.

Abstract (english)

This thesis demonstrates the changes on improved laboratory model compared to the old model, the problems that have arisen on the old scale model and the solution of these problems with an improved model. It is realized a circuit for measuring the current and the operation parameters (operating frequency, the input and output voltage, the extent of change in current) are set or the four switching power sources to allow simpler and more precise measurement of the current characteristic. It is also shown layout of the new circuit board and the waveforms of characteristic currents of all four switching power supply that has been measured in improved laboratory model.
