摘要
对 ５～１２ Ｖ 推挽式开关电容 Ｄ Ｃ Ｄ Ｃ 变换器的性能进行了理论分析及计算机仿真。结果表明，该结构的输出电流可达 １ Ａ 以上，效率优于 ７５ ％ ，输出电压纹波小于 ２０ ｍ Ｖ，具有高功率密度、便于集成等优点。
A theoretical analysis on the performance of 5～12 V push pull switched capacitor DC DC converters is presented and the computer simulation on the device is described. It is concluded that an output current up to 1 A, an efficiency better than 75% and an output voltage ripple less than 20 mV has been achieved for this topology. Furthermore, it features high power density and is easy for integration.
