Abstract
Изобретение относитс к электротехнике и может быть использовано в качестве низковольтного источника питани . Цель изобретени - повышение КПД. Ток зар да конденсатора 12 фильтра протекает через транзистор 2, который находитс в насыщении, а следовательно, имеет малое внутреннее сопротивление и работает в ключевом режиме. Выходное напр жение преобразовател определ етс стабилитроном 5. 2 ил.The invention relates to electrical engineering and can be used as a low voltage power source. The purpose of the invention is to increase efficiency. The charge current of the capacitor 12 of the filter flows through the transistor 2, which is in saturation, and therefore has a low internal resistance and operates in a key mode. The output voltage of the converter is determined by the Zener diode 5. 2 Il.
