Switched-capacitor-convertors based on fractal design for output power management of triboelectric nanogenerator. [PDF]
Nat Commun, 2020 AbstractOwing to the advantages of integration and being magnet-free and light-weight, the switched-capacitor-convertor plays an increasing role compared to traditional transformer in some specific power supply systems. However, the high output impedance and switching loss largely reduces its power efficiency, due to imperfect topology and transistors.
