Original Abstract

The paper presents a linear voltage controlled current source (VCCS) with +-5 A output current range, which will be used to excite applicator coils in experimental magnetic therapy. The VCCS was realized using a known topology with operational amplifiers and employs a slightly modified professional audio amplifier as output power buffer. The aim was to reduce the engineering effort needed to construct the source. The VCCS was supplemented with a simple signal generator with direct digital synthesis. These components form a compact instrument, which has been given the designation ZS1. Since the experiments are usually performed by researchers without background in electronics, the instrument is equipped with easy-to-use user interface.

Příspěvek popisuje lineární zdroj proudu řízený napětím (ZPŘN) s výstupním rozsahem +-5 A, který je určen k buzení cívek při experimentání magnetoterapii. Zdroj proudu byl realizován operačními zesilovačí pomocí známé topologie; jako posilovač výstupního proudu používá upravený audio zesilovač. Tento zesilovač byl použit pro snížení celkové složitosti návrhu zdroje. Zdroj proudu byl doplněn jednoduchým sginálním generátorem, který pracuje na principu přímé číslicové syntézy. Všechny tyto části tvoří kompaktní přístroj, kterému bylo dáno označení ZS1. Jelikož s přístrojem budou pracovat výzkumníci bez elektrotechnického vzdělání, je přístroj opatřen příjemným uživatelským rozhraním s alfanumerickým LCD displejem.
