Abstract
This paper presents the modeling and simulation of a DC-DC Buck Converter using MATLAB Simscape, aimed at achieving efficient voltage step-down conversion for various power electronics applications. The Buck Converter, widely employed in power supplies, provides a stable output voltage by converting a higher DC input voltage to a lower one with minimal losses. Using Simscape, an environment that allows for physical modeling of electrical systems, the paper demonstrates the design of the converter circuit, including key components such as the inductor, capacitor, switch, and diode, along with the control strategy for regulating the output voltage.The converter's performance is evaluated under varying load and input conditions, focusing on critical parameters such as output voltage ripple, efficiency, and transient response. The simulation utilizes Pulse Width Modulation (PWM) control for regulating the switch operation, ensuring output stability despite load fluctuations. The paper also explores the impact of component selection and system parameters on the overall performance. The results from the Simscape model are compared with theoretical calculations to verify the accuracy of the simulation and demonstrate the converter's reliability. This work highlights the effectiveness of using Simscape for rapid prototyping and performance evaluation in the design and optimization of DC-DC converters for a wide range of power electronics applications.Keywords: DC-DC Buck Converter, Simscape, PWM control, voltage regulation, efficiency, power electronics, simulation, transient response, load regulation, voltage ripple.
