Performance Analysis of a Newly Designed DC to DC Buck-Boost Converter

Abstract

Most of the electronic devices operate on the principle of the voltage-controlled voltage source. With the improved technology and an increase in circuit complexity, the necessity of controlling the output voltage level irrespective of the change in the load current or line voltage is increasing at a tremendous rate. Moreover, battery dominated electronic devices and gadgets demand a wide range of variation and control over DC voltage and power, which currently faces many challenges. This study proposes a design of a DC to DC Buck-Boost converter and analyzes the converter's performance by placing the Pulse Width Modulation of 40% and 48% duty cycles for buck-mode and 66% and 100% for boost-mode in the switching circuit. The result is simulated in the Proteus Suite software.
