Design Considerations for the Fast Charge of Supercapacitors in the Frame of Low Voltage Applications

Alfred Rufer, Philippe Barrade, Simon Delalay

Even if supercapacitors present a reduced energy density, they enable to store a significant amount of energy, which leads to a significant autonomy for applications with reduced energy needs. The main advantage of supercapacitors is there to compensate a ...
