Summary:
This paper presents a novel switched-capacitor dc-dc converters consisting of two sub-circuits connected in parallel. Switches in the circuit are controlled not only by periodic clock signal but also by a capacitor voltage. The voltage-controlled switching is a key to realize stable and variable output with fast transient. The circuit dynamics is described by piecewise linear equation and can be integrated into a 1-D return map: we can analyze the system dynamics precisely. Especially, it is clarified theoretically that the SC converter can realize superstable steady state with extremely fast transient.
