摘要

谐振开关电容变换器(RSCC)具有低开关损耗的特点，近年来受到越来越多的关注。然而，作为控制器设计的关键依据，RSCC的小信号模型研究却很少。本文首先介绍了相移控制下RSCC的工作原理。然后，基于扩展描述函数(EDF)方法研究了RSCC的小信号模型。采用小信号模型，设计了提高RSCC动态性能的控制器。最后，仿真和实验结果验证了小信号模型的正确性和所设计控制器的有效性。

Small Signal Modeling and Control of Resonant Switched Capacitor Converter

Featured with low switching loss, resonant switched capacitor converter (RSCC) has attracted more attention in recent years. However, as the key basis for controller design, the small signal model of RSCC is rarely studied. This paper firstly introduces the operation principle of RSCC under phase shift control. Then the small signal model of RSCC is studied based on the extended describing function (EDF) method. With the small signal model, the controller is designed to improve the RSCC dynamic performance. Finally, the simulation and experimental results verify the correctness of the small signal model and the effectiveness of the controller designed in this paper.
