Источники питания являются неотъемлемой частью любого радиоприемника, усилителя или другого аппарата, содержащего радиолампы.
Для питания цепей накала радиоламп применяются источники низкого напряжения (до 30 в). Питание анодных цепей и цепей экранирующих сеток радиоламп производится от источников с более высоким напряжением (до 250 в и выше).
Все существующие источники питания радиоламп можно разделить на четыре основные группы:
а) гальванические или первичные элементы;
б) аккумуляторы или вторичные элементы;
в) электросети переменного или постоянного тока;
г) ветроэлектрические установки.
Наиболее удобным источником питания радиоламп является электросеть переменного тока. Однако там, где ее нет, приходится пользоваться гальваническими элементами или аккумуляторами. Гальванические элементы или аккумуляторы также являются почти единственными источниками питания для различных передвижных портативных радиоприемников, радиостанций и другой аппаратуры.
Учитывая, что в любительских условиях питание радиоламп от ветроэлектрических установок и сети постоянного тока производится крайне редко, в настоящей брошюре рассматриваются вопросы питания радиоламп только от гальванических элементов, аккумуляторов и сети переменного тока.
Цель настоящей брошюры — ознакомить - начинающего радиолюбителя с устройством и типами гальванических элементов, аккумуляторов и способами использования сети переменного тока для питания радиоламп.
