An Improved Phase-Shift Control Method for Switched-Capacitor-Based Resonant Converter

This paper presents an improved phase-shift control method for a switched-capacitor-based resonant converter. Compared with the traditional phase-shift control, the proposed improved phase-shift control method can not only achieve soft-switching operation, but also fast start-up transient. The qualitative analysis based on the state plane proves that the convergence of the presented control method. The output voltage can be effectively regulated by adjusting the switching parameters. Simulation results verify the fast dynamic response of the switched-capacitor-based resonant converter with improved phase-shift control.
