提出了一种新型开关电容DC-DC变换器。该转换器由n个环形电容器组成，通过开关连接。与传统的SC变换器相比，该变换器具有以下特点：（1）一次只对一个电容充电，浪涌电流和输入电流涟漪小;（2）变换器的开关数量少;（3）所有浮地开关与接地开关形成图腾柱连接，易于驱动;以及（4）由于磁场的产生很少，与一些信号处理电路一起，可以以单芯片IC形式实现，例如片上系统。
A new switched-capacitor(SC) DC-DC converter is presented. This converter consists of n ring-shaped capacitors connected by switches. The converter has the following features as compared with conventional SC converters: (1) since only one capacitor is charged at one time, the inrush current and the input current ripple are small; (2) the converter has a smaller number of switches; (3) all floating switches form totem-pole connections with grounded switches, thus driving them is easy; and (4) since the generation of the magnetic field is few, together with some signal processing circuits, it is possible to be implemented in one chip IC form such as a system-on-chip.
