An Analysis Method for Design of a Cross-connected Fibonacci Switched Capacitor Converter

A switched capacitor converter (SCC) is designed without magnetic components, the characteristic of which can reduce circuit sizes and fit in portable devices. Among many types of SCCs, a cross-connected Fibonacci SCC (CCFSCC) was suggested but was analyzed, neglecting some circuit parameters such as its operation frequency and capacitance in previous studies. This study proposes an analysis method to optimize the CCFSCC, and to provide its hardware design guidance. From the proposed method, the operation frequency and capacitances of capacitors of the CCFSCC can be selected. To confirm the reliability of the suggested method, we compare the modeled and simulated results. The absolute difference between two outcomes is under 0.1 on average.
