Application of active diodes to enhance the efficiency and reliability of switching power supplies
Year: 2025
Type: article
Abstract: The paper deals with use of active (‘ideal’) diodes to improve the efficiency and reliability of switching power supplies. Traditional semiconductor diodes have significant energy losses due to forward voltage drop and reverse currents, which negatively affects the overall efficiency of systems, especially in low-voltage high-efficiency devices. Active diodes that use transistors and control circuitry enable achieving a low forward bias voltage drop and minimize reverse currents. Theoretical analysis and graphical dependences show significant reduction in power losses in rectifier elements using active diodes. Active diodes have significant potential for applications in various fields of electronics, especially in renewable energy and energy-efficient lighting, and are a promising area for further research and implementation in modern electronic systems.
