摘要：

A precise curvature-based, averaged modelling technique for two-phase switched-capacitor (SC) DC-DC converters is proposed. The generalized technique provides a complete characterization of the converter at steady-state for all operating conditions. From this model, a simple expression for the output impedance is obtained which relates the slow-switching limit and fast-switching limit impedances to the total output impedance. This expression can be used to accurately compute the output voltage without deriving the converter's state equations. The modeling technique is applied on a 1: 1 SC converter topology and compared with existing steady-state models. The accuracy of the model is validated through simulations and experimental measurements.
