基于开关电容变换器的水文遥测站供电系统设计

摘要

直流变换器（DC-DC）是新能源供电系统中必不可少的变换器。本文把开关电容电路融合到传统非隔离型直流变换电路中，形成高压比、高效率、高集成度的直流变换电路，可以更好地应用到水文遥测供电系统以及其他直流变换系统中。最后对新形成的拓扑进行理论推导分析和实验仿真分析，验证拓扑的正确性。%DC converter (DC-DC)is an essential converter in new energy power supply system.In the paper,switched-capacitor circuit is integrated to traditional non-isolated DC converter circuit to form DC converter circuit with high pressure ratio,high efficiency and high integration.It can be better applied to hydrologic telemetry systems and other DC conversion systems.Finally,theoretical derivation analysis and experimental simulation analysis can be conducted on newly-formed topology,thereby verifying the correctness of topology.
