Description

К нагрузке приложено напр жение, равное напр жению источника 9. При этом диод 3 заперт, ток в нагрузке начинает форсированно увеличиватьс , достига своего номинального значени , рост его прекратитс , когда управл юща схема запрёт транзистор 2. Ток нагрузки протекает через транзистор 1 и диод 3 под действием напр жени источника 8,A voltage equal to the voltage of the source 9 is applied to the load. At that, the diode 3 is locked, the current in the load starts to increase forcefully, reaches its nominal value, its growth stops when the control circuit blocks the transistor 2. The load current flows through transistor 1 and the diode 3 by the voltage of source 8,

При выключении управл ющей схемой транзистора 1 происходит отключение индуктивной нагрузки. После чего схема возвращаетс в исходное состо ние.When the transistor 1 is turned off by the control circuit, the inductive load is disconnected. The circuit then returns to its original state.

При подключении нескольких индуктивных нагрузок эмиттеры транзисторов 2 подключаютс к источнику высокого напр жени 9, эмиттеры транзисторов 1 - к источнику низкого напр жени 8 и обща точка соединени индуктивных нагрузок подключаетс к аноду диода стабилитрона 5 и общей точке соединени источников управл ющих сигналов 10 и 11.When several inductive loads are connected, the emitters of the transistors 2 are connected to the high voltage source 9, the emitters of the transistors 1 are connected to the low voltage source 8 and the common connection point of the inductive loads is connected to the anode of the Zener diode 5 and the common connection point of the control signals 10 and 11.
