摘要
论述一种新的开关电容ＤＣ－ＤＣ变换器的拓扑结构。在设计中采用两个附加的对称电容器以及相应的开关，以减少由于输出电容的等效串联阻抗造成的输出电压纹波电平。文中以一个１２Ｖ／５Ｖ的变换器为例讨论了这种方法。ＰＳＰＩＣＥ仿真和实验结果表明该方法是可行的。
This paper deals with a new topology of switched capacitor DC DC converter. In the new design, two additional capacitors with their corresponding switches are implanted, so as to eliminate the output voltage ripple caused by the equivalent series resistance of the output capacitor in traditional method. A 12V/5V converter is given as an example. The PSPICE simulation and experiment results show that the new design is feasible.
