Выбор параметров LC-фильтра для ШИМ сигнала

Abstract

Предложена методика инженерного расчета параметров LC-фильтра для высокочастотного ШИМ сигнала. Получены формулы локальной аппроксимации для основных инженерных характеристик фильтра: коэффициент гармоник, коэффициент эффективности, коэффициент жесткости характеристики. Локальная аппроксимация позволяет выбрать оптимальное соотношение между характеристиками фильтра. The procedure of engineering design of LC-filter parameters for high-frequency PWM signal has been proposed. The formulas of local approximation for basic filter engineering characteristics such as harmonic content, efficiency factor, characteristic stiffness factor are obtained. The local approximation makes it possible to choose the optimum relationship between the filter characteristics Сафонов Валерий Иванович – кандидат физико-математических наук, доцент, доцент кафедры «Системы электроснабжения», Южно-Уральский государственный университет.
