Abstract

Группа изобретений относится к питанию усилителей звуковых частот и звуковоспроизводящих комплексов от сети переменного тока. Технический результат - исключение обратной связи усилителя на сеть и влияния помех сети на качество работы усилителя- достигается введением дополнительного конденсатора, к которому подключают цепь питания усилителя, при этом дополнительный конденсатор подключают параллельно основному конденсатору через управляемый ключ и отключают от основного конденсатора на время подзарядки основного конденсатора от сети через выпрямитель.
