Abstract
Изобретение относитс к электротехнике и может быть использовано дл симметрировани режима перемагничивани выходного трансформатора в двухтактных преобразовател х источников вторичного электропитани . Цель - расширение функциональных возможностей. Устройство содержит двухтактный преобразователь 3 с выходным трансформатором 5, выпр мителем 6 и фильтром 7. Система управлени содержит задающий генератор 9, формирователь 10 защитной паузы, счетный триггер 11, элементы И 12,13, компаратор 14, дифференциальный усилитель 15, источник 16 опорного напр жени , второй компаратор 17, два последовательно соединенных конденсатора 18 и 19 формировател 20 длительности провод щего состо ни второго транзистора. Формирователь 20 состоит из двух элементов И-НЕ 21 и ИЛИ-НЕ 22, разр дных ключей 23 и 24 и переменного резистора 25. Блок 29 выделени тока намагничивани обеспечивает измерение тока в различные полупериоды в стационарном и переходных режимах. 2 ил.The invention relates to electrical engineering and can be used to balance the reversal regime of the output transformer in two-stroke converters of secondary power supply sources. The goal is enhanced functionality. The device contains a push-pull converter 3 with an output transformer 5, a rectifier 6 and a filter 7. The control system contains a master oscillator 9, a protective pause driver 10, a counting trigger 11, And 12.13 elements, a comparator 14, a differential amplifier 15, a reference source 16 The second comparator 17, two series-connected capacitors 18 and 19 of the driver 20, the duration of the conducting state of the second transistor. Shaper 20 consists of two elements, AND-HE 21 and OR-HE 22, bit switches 23 and 24, and a variable resistor 25. The magnetizing current extraction unit 29 provides current measurement in different half-periods in stationary and transient modes. 2 Il.
