Description

(S4) УСТРОЙСТВО дл  ПЕРЕКЛЮЧЕНИЯ ТОКА МАгаРТГНОЙ(S4) DEVICE FOR SWITCHING CURRENT MAGARTNAYA

головки Положительный импульс с коллектора транзистора 1 дгойупает на управл ющий вход ключа 4, а от{)йЦательньш - на управл ющий вход ключа 5. Ключ 4 замыкаетс , и токозадающий резистор 7 на вралю переходного процесса игунтируетс  ключом 4. При этом суммарный ток дифференциального переключател  на врем  переходного процесса возрастает , что приводит к повыщению напр жени  на голов ке и ускорению переключени  .тока. В описанном устройстве отсутствует несинфазность управл ющих сигналов, а его электрическа  схема значительно проще, чем у известных устройств Фор мула изобретени  Устройство дл  переключени  тока магнитной головки, содержащее дифференциальный переключатель тока, выходы которого соединены с полу обмотками магнитной головки, и источник тока с токозадающим резистором, параллельно которому включен форсирующий ключ, отличающийс   тем, что, с целью упрощени  схемы, параллельно токозадающему резистору включен второй форсирующий ключ, а управл ющие входы соединены с соответствующими выходами дифференциального переключател  тока. Источники информации, прин тые во внимание при экспертизе: 1.Патент США № 3763383, кл. 307-270, 1973. 2.Патент США № 2512171, кл. 346-74, 1970.The positive impulse from the collector of transistor 1 leads to the control input of switch 4, and from () it is applied to the control input of switch 5. Switch 4 closes and the resistor 7 to the transistor switch is played by switch 4. The total current of the differential switch during the transient process it increases, which leads to an increase in the voltage across the head and accelerate the switching of the current. In the described device there is no non-phased control signals, and its electrical circuit is much simpler than with the known devices Formula of the invention A device for switching the current of the magnetic head, which contains a differential current switch, whose outputs are connected to the floor of the magnetic windings, and a current source with a current-supply resistor in parallel with which the forcing switch is included, characterized in that, in order to simplify the circuit, a second forcing switch is connected in parallel with the current-setting resistor, and the control inputs are connected to the corresponding outputs of the differential current switch.
