Abstract

Cilj ovog rada je upoznavanje s klasama audio pojačala snage i njihovim mogućnostima.
U radu su navedeni principi rada svake od klasa kako bi dobili uvid u njihove međusobne razlike, a samim tim i razlike u korisnosti među klasama.
Za primjer pojačala snage konstruirano je pojačalo sa elektronskim cijevima koje radi u klasi A. U pojačalu se koriste dvije vrste cijevi. 6N6P koja se koristi u prvom i drugom stupnju pojačala te cijev 6S19P koja se koristi u izlaznom stupnju. Iako je konstruirano... More pojačalo male izlazne snage i malene iskoristivosti kvaliteta reprodukcije koju pruža na vrhunskoj je razini. Kod pojačala snage uvijek dolazi do kompromisa između kvalitete reprodukcije i koeficijenta iskoristivosti.

Abstract (english)

The aim of this paper is to introduce the class of audio amplifiers and their capabilities. The paper presents the principles of operation of each of the classes in order to get a glimpse of their differences , and therefore the difference in efficiency between classes. For example of power amplifier, power amplifier with electronic tube operating in Class A is designed. The amplifier used two types of tubes . 6N6P used in the first and second stage of amplifiers and 6S19P tube used in the... More output stage . Although designed amplifier have small output power and efficiency reproduction quality provided by the amplifier is top quality With the power amplifier it always come to a compromise between the quality of reproduction and the utilization coefficient .
