通过电容比优化提升堆叠开关电容能量缓冲器的能量密度

The recently proposed stacked switched capacitor (SSC) energy buffer architecture can extend the lifetime of single-phase ac-dc converters by replacing the electrolytic capacitors needed for twice-line-frequency energy storage with film or ceramic capacitors, while maintaining comparable effective energy density. This paper presents a methodology for further increasing the effective energy density...
