This article presents a state trajectory control scheme for switched-capacitor-based resonant converter consisting of two half-bridge circuits with four switches. The proposed technique can not only bring an improved dynamic response output voltage regulation but also ensure that the benefits from soft-switching operation. analysis in planes provides insight into switching modes and creates accurate behavior framework geometrical domain. As result, finite-state-machine controller is designed based on planning trajectories. conditions are exploited to obtain fast start-up step-load transient responses. method verified experimental results 14.5-V, 5.8-A prototype.
