Abstract
Glavna tematika pričajočega zaključnega dela je igralni avtomat, namenjen igri s kockami. Na njem sem kot osrednjo problematiko izpostavil optimizacijo delovanja zaščitnih naprav, ki ob previsokem električnem toku oziroma previsoki napetosti zagotavljajo avtomatski izklop igralnega avtomata v čim krajšem času. Igralni avtomat vsebuje 6 različnih zaščit: osnovna elektronska tokovna zaščita, dodatna elektronska tokovna zaščita, kratkostična elektronska tokovna zaščita, osnovna programska tokovna zaščita, termična programska zaščita in zaščita ob previsoki napetosti iz DC/DC pretvornika. Vse omenjene zaščite sem podrobno opisal in predstavili parametre, ki omogočajo hitro in zanesljivo delovanje. Na koncu sem še opravil funkcionalni preizkus, s katerim sem preveril in potrdili delovanje zaščit.

Title:Optimization of the protection of the electronic module for controlling the loudspeaker coil
Abstract:
The main topic of this diploma thesis is the dice slot machine. My main focus is the optimisation of protection devices operation, which in the case of electrical overcurrent or overvoltage ensure the automatic shut off of the slot machine in the shortest possible time. The slot machine has 6 protections: basic electronic current protection, additional electronic current protection, short circuit protection, basic software circuit protection, thermal software protection and protection in case of overvoltage from the DC/DC converter. All of the above mentioned protections were described in detail and parameters, which enable fast and reliable operation, were introduced. Finally, I have performed a functional experiment to evaluate and confirm the operation of protections.

Keywords:Slot machine, surge protection, thermal protection, operational amplifiers
