一种高升压比直流变换器

摘要

在分析两类升压型直流变换器拓扑结构的基础上，结合耦合电感类拓扑结构与带自举结构的Luo变换器的特点提出一种高升压比的升压型直流变换器拓扑结构。文中分析了这种拓扑结构工作原理，并且讨论了拓扑在连续模式和断续模式下的工作状态。设计了拓扑的主要参数，并通过实验验证了理论的正确。%Based on two types of step-up DC-DC converter topologies, this paper proposes a type of single input double output high step-up converter which combined coupled inductor with Luo converter. Work condition of new topology is researched, and continuous conduction mode and discontinuous conduction mode is studied. Parameter of proposed topology is designed, and experiment validates correction of the theory.
