本文对一种电压模式控制的混合型开关电容变流器进行了分析和控制器设计。采用状态空间平均法建立了开关频率高达一半的小信号模型，并采用环路增益设计了电压模式反馈补偿。分析了一种混合型开关电容变流器的闭环性能。通过计算机仿真，给出了控制器设计和闭环分析的结果。为了验证控制器的设计和分析，提供了一个28V应用下的原型开关电容转换器的实验观测
In this paper analysis and controller design of a voltage-mode controlled of hybrid switched capacitor converter is presented. The state-space averaging method is applied to formulate the small-signal models, valid up-to half of the switching frequency, of the converter and a loop gain is adapted to design the voltage-mode feedback compensation. Closed-loop performance of a hybrid switched capacitor converter is analysed. The results of controller design and closed-loop analysis are illustrated through computer simulations. To validate the controller design and analysis, experimental observations of a prototype switched-capacitor converter are provided for 28 V applications
