Multi-stage multi-level direct-current power supply architecture based on switched capacitors

The invention discloses a multi-stage multi-level direct-current power supply architecture based on a switched capacitor, the power supply architecture comprises an input source, a first power conversion part, a switching network and a second power conversion part, and the first power conversion part is a converter structure with a fixed voltage conversion ratio and comprises a switched capacitor type circuit with the stage number of n. The switch network is a circuit structure with multi-port input and dual-port output, and the second power conversion part is a three-port circuit with dual-port input and single-port output. The power supply architecture can reduce the swing amplitude of a switching point, reduce the size of an inductor, and improve the power density and efficiency. The method is suitable for power supply application in the modern SOC calculation field. 本发明公开了一种基于开关电容的多级多电平直流电源架构，该电源架构包括输入源、第一功率变换部分、开关网络和第二功率变换部分，其中第一功率变换部分是一个固定转压比的转换器结构，包含一个级数为n的开关电容型电路。开关网络是一个多端口输入、双端口输出的电路结构，第二功率变换部分是一个双端口
