Small Signal Modeling of Switched Tank Converter with Partial Power Voltage Regulation

In order to better control the closed-loop control of Switched Tank Converter with Partial Power Voltage Regulation (PPVR-STC), this paper proposes a small signal modeling method for two kinds of PPVR-STC, which based on the working principle of PPVR-STC and through a series of simplifications. The accuracy of the small signal model is verified by comparing the bode figures obtained by sweeping the frequency of the simulation circuits with the bode figures of the small signal equivalent circuits after simplification, which provides a theoretical basis for closed-loop control.
