According to capacitance energy storage formula, E (energy of capacitance stores)=C (capacitance of electric capacity) * U2 (voltage effective value)/2 obtains:
When capacitance voltage effective value U=5.5 lies prostrate (meeting general handheld device cell voltage), the capacitance C=0.4 farad of electric capacity.Consider internal resistance and the tolerance of electric capacity, simultaneously in conjunction with the discharge and recharge time, therefore, can by capacitance selection at 0.8 ~ 1.2 farad.
