摘要
锂电池、光伏电池、燃料电池等新型储能器件的发展,对直流变换器的纹波和增益性能有了更高的要求。为此提出了一种结合三电感与开关电容的高增益Boost变换器拓扑组合,该拓扑结构基于三电感单管高增益Boost变换器,通过在后侧增加开关电容网络,可保证单管在相同占空比条件下实现更高的电压增益,并通过理论分析和仿真实验进行了验证。
With the development of lithium batteries,photovoltaic cells,fuel cells,and other new energy storage devices,higher requirements are put forward for ripple and gain performance of DC converter.In this paper,a topology combination of a triple-inductor and switching capacitor for a high-gain Boost converter is proposed.The topology is based on a triple-inductor single MOSFET high-gain Boost converter.By adding a switching capacitor network on the rear side,higher voltage gain can be achieved under the same duty cycle condition of a single MOSFET.In addition,theoretical analysis and simulation experiments verify that this topology has higher voltage gain under the same duty cycle.
