Study of the DC/DC Boost Converter Physical Model

Abstract

The paper is devoted to the design of DC/DC boost converter physical model. Circuit diagram as well as the principle of work and features of components selection for the purpose of design are presented. The recommendations to the problems related to design and assembly of boost converter and its components are given. The calculation technique and design of boost converter main parameters are presented. Detailed attention is paid to control system design which was implemented on Arduino-based Atmega microcontroller. The operational states of converter under design as the component of testing bench are analyzed. Relying upon the obtained results converter operation performance was measured. The results of a study of the assembled DC/DC boost converter in an experimental stand are presented, where its operating modes are analyzed in detail and the features of controlling a transistor key at elevated frequencies are studied. The proposed step-up converter is designed to solve the problem of providing power to various voltage levels in electrical appliances and devices using highly efficient power switches. In addition, the use of control systems based on programmable microcontrollers makes it possible to change the parameters of control signals in real time, thereby adjusting the output parameters of the converter, primarily voltage.
