Abstract
The present invention discloses charging devices for charging energy-storage devices. Charging devices include: an Electro-Magnetic Interference/Radio-Frequency Interference (EMI/RFI) filter for passively suppressing conducted interference present on an alternating-current (AC) power source; optionally, a transformer for transforming power from the AC power source without changing frequency; a rectifier for converting an AC input to a direct-current (DC) output; and a voltage-controlled charger for providing a high-power output having an output voltage and an output current from the AC power source, wherein the output voltage and the output current from the voltage-controlled charger are pulsating DC signals. Preferably, the high-power output has a power-factor value of: greater than about 0.70, greater than about 0.80, greater than about 0.90, greater than about 0.95, or greater than about 0.97. Preferably, the high-power output is a wattage of: greater than about 40W, greater than about 50W, greater than about 60W, or greater than about 70W.
