Non-Isolated Dual-Output Mirror-Symmetric DC-DC Converters: Topology Construction and Analysis

Abstract

This paper proposes an improved series of a revolutionary mirror-symmetrical dual-output non-isolated dc-dc converter using the voltage lift approach. Its unique design offers a series of improvements that set it apart from traditional converters. The converter's basic architecture allows for substantial voltage transfer gains when converting dc-dc voltage, not just from positive to positive, but also from positive to negative. This flexibility sets it apart from other dual-output dc-dc converters currently available on the market.A key advantage of this converter is its simplicity. All suggested topologies employ a single power switch, eliminating the need for transformers or cascade connections. This simplicity could make it an attractive option for future practical applications. The shared ground design ensures more dependable dual-output voltages, further enhancing the converter's reliability.The theoretical foundation of this converter is rock solid, with a thorough topology analysis conducted for both discontinuous and continuous conduction modes. This analysis provides a solid foundation for understanding the converter's operation and its potential for real-world applications.To validate the suggested topologies, experimental results and simulations are presented. These results demonstrate the converter's effectiveness and confirm its theoretical advantages. They also highlight its adaptability to different operating conditions, making it a versatile solution for a range of dc-dc voltage conversion needs.
