The Analysis of DCDC BUCK Circuit based on Arduino

Abstract

With the development of the times, digitally controlled power supplies are becoming the trend of today's DC power supplies. This paper details a step-down circuit with Mosfet switch controlled by Arduino. This power supply and DC-DC adopts advanced semiconductor technology and digital control technology, featuring small size, light weight, simple and easy adjustment, high efficiency, wide voltage range and complete shutdown of zero-point adjustment. First, this paper details the structure, principle, and many features of the Arduino platform. Second, this paper explains the principle of BOOST circuit for boost and BUCK circuit for buck with equations and structure diagrams, and presents real-life applications. By reading this article, beginners will have a basic understanding of the use of Arduino and know what the exact principles of this circuit are, as well as circuit design and software programming ideas.
