Abstract
Conventional switched capacitor converters have an inherent drawback that their efficiency is much decreased as the output current is increased. To solve this problem we presented a novel switched capacitor converter topology that uses a resonant operation instead of the forced charging and discharging operation. Its advantage over a conventional switched capacitor converter is a high efficiency even in a high output current region. In this paper, firstly, the operation analysis and the steady-state characteristics are analyzed for a double boost type switched capacitor converter with synchronous rectifiers under the condition that the switching frequency matches with the resonant frequency. Next, the steady-state characteristics are analyzed when using the output voltage control by changing the switching frequency.
