Аннотация. Предложена математическая модель осциллятора Колпитца на основе системы дифференциальных уравнений, описывающих динамику автогенератора с учетом паразитных электродвижущих сил, наводимых внешним электромагнитным полем в различных контурах схемы. Актуальность исследования обусловлена усложнением современной электромагнитной обстановки и миниатюризацией электронных компонентов, приводящей к снижению их помехоустойчивости. Показано, что кратковременное импульсное воздействие способно вызывать фазовый сдвиг колебаний осциллятора. Установлено, что величина этого фазового сдвига зависит от амплитуды помехи, момента ее приложения и контура, в который она вводится. С помощью численных экспериментов выявлены наиболее уязвимые участки схемы, что может быть использовано при проектировании помехоустойчивых автогенераторных схем и оптимизации их топологии.

Ключевые слова: электромагнитная совместимость, осциллятор Колпитца, автогенератор, фазовый сдвиг, электромагнитная восприимчивость, импульсная помеха, численное моделирование.
