摘要：

This paper presented a voltage regulation method for high power switched-capacitor converters. The proposed method is based on a LC equivalent circuit of the capacitor charging loop, instead of the traditional RC equivalent circuit. The output voltage is regulated by varying the duration of the sinusoidal charging current. With the third quadrant operation of MOSFETs and optimized capacitor charging loop, the efficiency of the converter with the proposed voltage regulation method can exceed the theoretical maximum efficiency value for traditional methods. Detailed analysis and experimental results on a 200 W prototype is included in this paper.
