摘要：
A flying capacitor based n-level non-isolated DC-DC converter is researched in this paper. The converter features reduced flying capacitors, compact structure, adjustable output voltage and high-voltage high-power ability. Basic operating principle was analyzed and a mean value model is derived. A dual-loop capacitor voltage balancing method for n-level structure is proposed. A seven-level prototype was built up, both steady and dynamic experimental results are presented to verify this method.
