Evaluation of Conducted Noise of Resonant Switched Capacitor Converter

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
