Abstract:
A battery charger adapted to increase a charge current applied to at least one battery from a predetermined supply voltage, comprising:supply voltage generating means coupled to an AC voltage source for generating the predetermined supply voltage; anda charging circuit electrically connected to said supply voltage generating means and including a first capacitor and a second capacitor AC coupled to the first capacitor, said charging circuit being adapted to apply the charge current from said supply voltage generating means to the at least one battery through said first capacitor during a first half of a charging cycle, and store the charge current from said supply voltage generating means in said second capacitor during a second half of said charging cycle and apply the charge current to the at least one battery during the first half of the charging cycle, to increase the charge current applied to the at least one battery during said first half of said charging cycle.
