Abstract:
A battery charger comprising input terminals for connection to an AC source, output terminals for connection to a battery to be charged, and a power factor correction (PFC) circuit connected between the input terminals and the output terminals. The PFC circuit comprises a current control loop for regulating an input current drawn from the AC source. The voltage at the output of the PFC circuit is regulated by the voltage of the battery which is reflected back to the PFC circuit. As a result, the battery charger acts as a current source that outputs an output current at the output terminals, and the waveform of the output current is periodic with a frequency twice that of the input current and a ripple of at least 50%.

Claim (Index 6):
The battery charger of  claim 1 , wherein the battery charger operates in a first mode when the voltage of the battery is less than a threshold, the battery charger switches to a second mode when the voltage of the battery exceeds the threshold, the AC source supplies an alternating input voltage, the PFC circuit causes the input current to be drawn from the AC source during each half-cycle of a plurality of half-cycles of the input voltage when operating in the first mode, and the PFC circuit causes the input current to be drawn from the AC source during only some of the half-cycles of the input voltage when operating in the second mode.
