This article delves into controlling DC/DC energy conversion using a Boost converter linked to a fuel cell; crucial for maintaining efficient energy transfer by ensuring the output voltage (VO) remains higher than the input voltage (VI). The converter integrates components such as inductance (L), diode (D), capacitor (C), and resistive load (RL) to ensure reliable operation. Various control strategies, notably fuzzy logic control, are evaluated to enhance the Boost converter’s performance. By comparing these strategies with traditional methods, the study aims to uncover their respective strengths and weaknesses in real-world applications. This comparative analysis provides insights into optimizing DC/DC energy conversion, essential for advancing renewable energy systems like fuel cells. The research emphasizes stabilizing output voltage at a 48V reference amidst load variations, observed through simulations yielding satisfactory results (Fig. 5). Adjustments in fuzzy PID controller gains effectively stabilize system responses, demonstrating practical benefits in converter dimensioning and performance enhancement. These findings contribute significantly to developing advanced and dependable energy conversion technologies, pivotal for maximizing the efficiency and reliability of renewable energy sources.
