Использование антиалиасингового фильтра в цифровых системах управления преобразователями электрической энергии

Abstract

Anti-aliasing filters are used to exclude mixing spectra in systems with digital signal processing. Digital control system of electric power converters, as real-time systems, applies additional restrictions to the response of these filters. The paper defines features of the application of anti-aliasing filters in real-time systems. Mathematical modeling of the most common types of filters in the application to digital control systems has been made. The requirements to the characteristics of filters, depending on the spectral composition of the input signal have been formulated.
