Study on Sneak Circuit in Switched Capacitor Resonant Converter with Controllable Output

Sneak circuit in switched capacitor resonant converter with controllable output was investigated.Sneak circuit mode in switched capacitor resonant converter and its exciting conditions were discussed.And methods to restrict effect of sneak circuits were proposed.Simulation was made to verify the analysis.It has been demonstrated that output power of the converter was restricted by sneak circuits,and that restrictive methods were useful for improving system response and suppressing interference of power supply and load variation.
