Claim Text:
1. A high-power charging device for charging energy-storage devices, the high-power charging device comprising: (a) an Electro-Magnetic Interference/Radio-Frequency Interference (EMI/RFI) filter for passively suppressing conducted interference present on a received alternating current (AC) power source; (b) a transformer directly coupled to the EMI/RFI filter for transforming the power from said AC power source without changing frequency; (c) a rectifier directly coupled to the transformer without an electronic switching circuit in between for converting the rectifies the transformed AC power source into a waveform that ranges from zero to positive volts a; and (d) a voltage-controlled charger directly coupled to the rectifier without a capacitor in between for providing a power output that is greater than 40 W, the power output comprising an output voltage and an output current that range from zero to positive volts or amps, respectively.
