Research on Ripple Suppression of Switching Power Supply Based on Computer Simulation Software Multisim

Abstract

In an era of rapidly advancing computer software technology, its role is increasingly fundamental in addressing the challenges of ripple in electrical power sources originating from switching types of power supplies. This article aims to examine in detail the causes of ripple generation, the various methods used to overcome such ripple, as well as the relevant circuit designs in the Multisim simulation environment. In addition, this research will also explore various relevant simulation analysis methods. Ripple is a periodic fluctuation in voltage and current in power circuits, and is often a serious bottleneck in the reliability of electronic systems. In this context, this article will discuss the underlying causes of ripple, such as the characteristics of the components involved in switching power supplies and the role of impedance in circuits. We will dive into methods that have been developed and widely applied in industry to control ripple, such as the use of capacitors, inductors, and active filters. Furthermore, this research will provide insights into circuit design with the help of Multisim simulation software, which is a very useful tool for virtually testing and analysing power circuits before implementing them in the real world. We will discuss concrete steps as well as strategies applied in circuit design that are effective in reducing ripple in power supplies. Finally, this article will highlight various simulation analysis methods that can be used to evaluate circuit performance and the effectiveness of the ripple control measures taken. It is hoped that this research will make a valuable contribution to professionals who seek to maintain the stability and reliability of modern electronic systems by addressing the issue of ripple in switching type power supplies.
