非耦合 SC Cuk DC-DC 变换器的临界条件

Boundary Conditions of Decoupled SC Cuk DCDC Converter

非耦合开关电容ＣｕｋＤＣ－ＤＣ变换器（ＳＣＣｕｋＤＣ－ＤＣ变换器）和普通ＣｕｋＤＣ－ＤＣ变换器相比，其输入输出电感可工作在独立的导电模式。由于它的导电模式不同于任何现有的变换器，因此本文对这种变换器的临界条件进行了详细分析。实验结果证实了理论分析。

Unlike the input and output inductors in conventional Cuk DCDC converter,these two inductors in decoupled switched capacitor(SC) Cuk DCDC converter can work at the independent conducting mode.The conducting mode of the proposed DCDC converter is different from any existing DCDC converters,so the boundary conditions of the proposed converter are analyzed in detail.It is proved that the theoretical analysis is identical with the experimental results.
