Abstract

Bu çalışmada, dinamik bir sistemin keyfi bir durumdan, ihtiyaç duyulan çıkış voltajı değeri tarafından belirlenen bir duruma iki aşamalı bir geçişini sağlayan, düşürücü bir voltaj dönüştürücünün bozucu etkilere tepkisinin matematiksel modellenmesi analiz edilmektedir. Entegre uyarlamalı birleştirilmiş denetleyicilerin analitik yapı yöntemi (ACAC) kullanılarak, DC sürekli akım modunda ve güç anahtarının sabit frekans değeri için bir düşürücü voltaj dönüştürücüsü sentezlenmiştir.

Mathematical Modeling of the Response of a Buck Converter to Disturbances

Abstract

This study discusses the issues of mathematical modeling of the response of a step-down voltage converter to disturbing influences, which provides a two-stage transfer of a dynamic system from an arbitrary state to a state determined by the required output voltage value. Using the method of analytical construction of aggregated controllers (ACAC) with integral adaptation, a regulator of a buck converter in DC mode (CCM) and a constant frequency of the power switch is synthesized.

Keywords

Buck converter, Continuous current mode (CCM), Control system, Integral adaptation method, Pulse Width Modulation
