本文介绍了一种用于复杂开关电容（SC）转换器的新分析技术。它使用传统的电路分析方法来导出每种开关模式的状态空间模型。导出稳态性能并将其表示为等效电阻。以前的技术要么提供了简单 SC 转换器的详细性能，要么提供了复杂 SC 转换器的限制性能，而这种新方法足够灵活，可以为任何实际转换器提供详细性能。不均匀的元件选择、不对称的占空比以及与理想转换器的其他偏差都可以很容易地包括在内。还可以分析动力学。该模型已通过模拟技术和实验室测试收集的实验数据得到验证。
This paper introduces a new analysis technique for complex switched-capacitor (SC) converters. It uses conventional circuit analysis methods to derive state-space models of each switching mode. Steady-state performance is derived and expressed as an equivalent resistance. Whereas previous techniques have provided either the detailed performance of a simple SC converter or the limiting performance of a complex SC converter, this new method is flexible enough to provide detailed performance for any practical converter. Nonuniform component choices, asymmetric duty cycle, and other deviations from an ideal converter can be readily included. Dynamics can also be analyzed. The model has been validated through simulation techniques and experimental data collected from laboratory testing.
