Схемотехнические решения проверяются функциональными тестами. Так схемы новых пассивных корректоров, методов стабилизации тока светодиода и т. д. проверяются на достижение желаемых функциональных характеристик при различных условиях работы драйвера. Условиями работы, например, являются изменяемое входное сетевое напряжение, температура окружающей среды, холостой ход, условие короткого замыкания, величина выходной нагрузки, динамические процессы и т. п. Каждое схемотехническое решение имеет свои целевые функциональные параметры, которым будет уделяться внимание в тестах. Основные целевые отображения схемы стабилизации тока - точность стабилизации и К. П. Д.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work is to research the existing concepts and circuit solutions for LED drivers. Circuit solutions are tested by functional tests. So the scheme ofnew passive correctors, methods for stabilizing the LED current, etc. are tested to achieve the desired functional characteristics under various conditions of the driver. The working conditions, for example, are variable input mains voltage, ambient temperature, idle speed, short circuit condition, output load, dynamic processes, etc. Each circuit solution has its own target functional parameters, which will be paid attention to in tests. The main target displays of the current stabilization scheme are stabilization accuracy and efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейный</kwd><kwd>импульсный драйвер</kwd><kwd>генератор тока</kwd><kwd>стабилизатор тока</kwd><kwd>гальваническая развязка</kwd><kwd>светодиодная цепь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>linear</kwd><kwd>pulse driver</kwd><kwd>current generator</kwd><kwd>current stabilizer</kwd><kwd>galvanic isolation</kwd><kwd>LED circuit</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">http://ledno.ru/.</mixed-citation><mixed-citation xml:lang="en">http://ledno.ru/.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">http://diode-system.com/.</mixed-citation><mixed-citation xml:lang="en">http://diode-system.com/.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">http://www.ti.com/.</mixed-citation><mixed-citation xml:lang="en">http://www.ti.com/.</mixed-citation></citation-alternatives></ref><ref id="cit4"><label>4</label><citation-alternatives><mixed-citation xml:lang="ru">Hwu K.
