Abstract
Использование: в источниках вторичного электропитани радиоэлектронной аппаратуры . Сущность изобретени : при подаче напр жени питани через первый пусковой резистор 14 приоткрываютс ключевой 6 и размыкающий 20 транзисторы Ток в обмотке 2 дроссел 1 нарастает по линейному закону до тех пор, пока напр жение на датчике тока 7 не окажетс достаточным дл включени коммутирующего транзистора 8, шунтирующего входные цепи ключевого 6 и коммутирующего 20 транзисторов Напр жение на обмотках многообмоточного дроссел 1 мен ет пол рность и энерги дроссел расходуетс на зар д конденсаторов выходной цепи и цепи обратной св зи. Процессы переключени ключевого 6 и размыкающего 20 транзисторов фиксируютс дополнительной обмоткой 3 многообмоточного дроссел 1. 1 ил.Usage: in the sources of secondary power of electronic equipment. Summary of the invention: when the supply voltage is supplied through the first starting resistor 14, the key 6 and disconnecting transistors 20 are opened. The current in the winding 2 of the jumper 1 increases linearly until the voltage on the current sensor 7 is sufficient to turn on the switching transistor 8. shunting the input circuits of the key 6 and switching 20 transistors The voltage on the windings of the multi-winding circuit 1 changes polarity and the energy of the circuit is consumed by charging the capacitors of the output circuit and the feedback circuit zee. The switching processes of the key 6 and the disconnecting 20 transistors are fixed by the additional winding 3 of the multi-winding drossel 1. 1 ill.
