摘　　要：针对低压蓄电池供电系统,设计了两级升压变换电路的拓扑结构,该拓扑结构由Boost TL三电平升压电路和Full-Bridge全桥电路构成,通过对两个升压环节进行调节使其输出达到所需要求。此拓扑结构相对于普通一级变换电路来说具有一定的优越性,通过理论分析、仿真、试验结果验证了此拓扑结构的可行性。A new two - step voltage transformation DC-DC converter＇ s topology is designed which is used in low battery power supply system. It is composed by Boost three-level and Full-Bridge circuits which can adjust output voltage to meet design demands by two steps. The eonveter has some advantages than general one-step voltage transformation DC-DC converter＇ s circuit. It proved that the topology circuit was feasible by the theoretical analysis. simulation and experiments.
