Implementing a Buck-Boost Converter in MATLAB

This article provides a comprehensive guide on implementing a Buck-Boost converter using MATLAB. The Buck-Boost converter is a power electronics device capable of converting DC voltage to required voltage levels, with broad practical applications. We begin by explaining the fundamental principles and operational modes of Buck-Boost converters. Subsequently, we demonstrate how to program this converter using MATLAB's Simulink environment and scripting capabilities, including key functions like ode45 for differential equation solving and PWM signal generation techniques. The implementation will cover component modeling (inductors, capacitors, switches), control loop design using transfer functions, and real-time simulation configuration. Finally, we explore performance optimization strategies through parameter tuning algorithms and efficiency calculations, enabling practical application with optimal results. Through this tutorial, you'll gain thorough understanding of Buck-Boost converter operation and MATLAB implementation techniques for power electronics systems.
