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 7):
The battery charger of  claim 1 , wherein the AC source supplies an alternating input voltage, and the battery charger comprises a step-down DC-to-DC converter having a voltage conversion ratio greater than a peak value of the input voltage divided by a minimum voltage of the battery.
