Abstract

Изобретение относитс к импульсной технике. Цель изобретени - повышение линейности и увеличение крутизны спада формируемого напр жени . В формирователь, содержащий блок 1 управлени , источник 3 опорного напр жени , интегратор 4, интегратор 6 со сбросом, компаратор 8, электронный ключ 10, сумматор 20, введены триггер 2, интегратор 5, интегратор 7 со сбросом, компаратор 9, электронные ключи 11-13, элементы И 14-17, элементы НЕ 18,19, сумматор 21. Интеграторы 4,6, компаратор 8 и электронный ключ 10, а также интеграторы 5,7, компаратор 9 и электронный ключ 11 образуют два формировател пилообразного напр жени , работающие в противофазе и обеспечивающие стабильную амплитуду при изменени х частоты импульсов на входной шине 22. Через электронные ключи 13 и 12 на сумматор 21 поступают только нарастающие пилообразные сигналы, в результате на выходной шине 23 формируетс пилообразное напр жение с крутым спадом. 2 ил.The invention relates to a pulse technique. The purpose of the invention is to increase the linearity and increase the slope of the generated voltage. A driver that contains a control unit 1, a voltage source 3, an integrator 4, an integrator 6 with a reset, a comparator 8, an electronic switch 10, an adder 20, a trigger 2 is entered, an integrator 5, an integrator 7 with a reset, a comparator 9, electronic switches 11 -13, elements AND 14-17, elements NOT 18.19, adder 21. Integrators 4.6, comparator 8 and electronic key 10, as well as integrators 5.7, comparator 9 and electronic key 11 form two sawtooth voltage drivers, working in antiphase and providing a stable amplitude with impulse frequency changes There are only increasing ramp signals on the input bus 22 through the electronic keys 13 and 12, and as a result a ramp voltage is formed on the output bus 23. 2 Il.
