Оценка качества передачи гармонического воздействия в многозонных преобразователях с двухтактной широтно- и частотно-широтно-импульсной модуляцией

Abstract

Приводятся результаты сопоставительного анализа качества передачи гармонического сигнала в двухтактных многозонных развертывающих преобразователях (МРП) с различными законами модуляции. Рассматриваются МРП с широтно-импульсной модуляцией и с частотно-широтно-импульсной модуляцией. Приведены структурные схемы, временные диаграммы сигналов преобразователей при гармоническом входном воздействии, основные расчетные соотношения, а также характеристики, полученные в результате моделирования в среде Matlab+Simulink. Результаты исследований могут представлять интерес для специалистов в области силовой и информационной электроники, электропривода и автоматизации технологических процессов. The results of a comparative analysis of transmission quality of the harmonic signal in push-pull multizone sweep converters with the modulation of two types are considered in this article. Multi-zone sweep converters with width-pulse modulation and frequency-width-pulse modulation are shown. The structure charts of the multi-zone converters, its time diagrams for harmonic input signal, main analytical expressions and characteristics obtained as a result of a modeling in Matlab + Simulink are given. This article may interest specialists in the field of power and information electronics, of the electric drive and automation of technological processes.
