N2 - Bidirectional DC/DC converters have important application value in energy storage system.compared with conventional topology, switched-capacitor-based non-isolated DC/DC converter inherently possesses good static characteristics including lower voltage and current stress of power switches, higher voltage boost capability and continuous input/output current. However, its control-to-output transfer functions contain Right-Half-Plane Zeros in both boost conversion and buck conversion mode, which considerably constrains the compensator design and further limits the dynamic performance of the closed-loop system. In this paper, it is proposed to use RC damping method to address the issue, which enables to effectively eliminate the Right-Half-Plane Zeros under both conversion modes and thus improve the system's dynamic performance. Theoretical analysis and simulation results are provided in the paper.
