This paper investigates the recent developments on switched-capacitor converters for high power applications. Based on an analysis on the shape of capacitor charging current for switched-capacitor converters, technologies used to improve the efficiency and reduce the Electromagnetic Interference (EMI), including the soft-switching and interleaving scheme, are discussed. Several existing topologies...
In this paper, several modular converter topologies based on a switched-capacitor-cell concept are introduced for high-power applications. Two types of switched-capacitor cells, including the full cell and the half-cell, are discussed. The full cell can be used for dc–ac inversion, and the half-cell is utilized in both dc–dc and dc–ac applications. A rotational charging scheme is adopted for the half-cell-based...
