A NEW BUCK-BOOST CONVERTER WITH HIGH VOLTAGE CONVERSION RATIO AND REDUCED VOLTAGE AND CURRENT STRESS ON SWITCHES AND DIODES

Abstract

This study presents an improved Buck-Boost converter configuration capable of achieving a high voltage conversion ratio while significantly reducing voltage and current stress on critical components such as MOSFETs and diodes. The proposed design enhances operational efficiency, extends component lifespan, and ensures maximum system reliability. To provide an objective assessment, experimental evaluations were conducted to compare output voltage overshoot, input current characteristics, and overall efficiency with existing converters. The results demonstrate that the proposed converter not only overcomes the limitations of conventional topologies but also maintains high efficiency and stable operation across a wide voltage conversion range. With these advantages, the proposed design holds strong potential for applications requiring high performance and long-term stability.
