Abstract
- This paper presents an analytical method to evaluate pertinent data of the resonant capacitive switching converter, especially the voltage gain and power efficiency. Instead of long transient simulation time, the proposed model uses frequency decomposition to speed-up computation. This method is valid for N-phase operation, and extends the recently published studies on this promising topology outside zero-current/voltage switching conditions. Thanks to this tractable expression, we also reveal the intrinsic efficiencies over the voltage gain of two- and three-phase structures working at the resonant frequency in step-down operation. These results help to gain better understanding of multiphase operation, and encourage additional studies to use the full capability offered by the resonant-switched capacitor converter especially for power on-chip integration.
