Investigation of a DC voltage boost converter based on a multifunctional integrated electromagnetic component

Abstract

Abstract The methods of functional integration of discrete electrical and electromagnetic components allow to increase the reliability and efficiency of electrical energy conversion systems, to reduce their weight and dimensions. The authors proposed a solution based on replacing some individual discrete components of a DC voltage boost converter with a multifunctional integrated electromagnetic component (MIEC). The component acts as an inductor and filter capacitor. A computer model of a DC voltage boost converter based on MIEC in the MatLab software package has been developed. The graphs of the output voltage are obtained. The circuits of step-up converters of constant voltage are analyzed. The optimal for the implementation of the replacement of the inductor and the filter capacitor with a multifunctional integrated electromagnetic component has been chosen. A circuit of a DC voltage boost converter based on MIEC is assembled. Oscillograms of the output voltage were taken. The analysis of the computer model and laboratory test sample was carried out.
