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 resonant switched capacitor converter topology that uses a resonant operation instead of the forced charging and discharging operation. Its advantages over a conventional switched capacitor converter are a high efficiency and a low switching noise. In this paper, the operation analysis and steady-state characteristics are briefly reviewed for a boost type switched capacitor converter, and conducted noise characteristics are investigated experimentally
