Ověření funkce ochranného obvodu na impulsním signálu simulujícím zmenšený koagulační signál - laboratorní úloha

Abstract

The aim of the bachelor thesis was to create a laboratory task that demonstrates to students the functions of several protection circuits on an impulse signal simulating a reduced coagulation signal. The bachelor's thesis first describes the theoretical study of protective circuits. Furthermore, the design of a laboratory task is carried out, the purpose of which is to show students what types of protection circuits exist, both against overvoltage and against electromagnetic interference. From this laboratory task, students will gain knowledge about the principle of function of individual elements of protective circuits and their effectiveness in suppressing interfering signals or overvoltage impulses. The student works out the laboratory task using an oscilloscope, a reduced coagulation signal source and protective circuits, which are the content of this work. The student then processes the results on the computer.
