System and circuit for recharging large capacity batteries

摘要

A system and circuit for recharging a battery using an AC power source. A tuned circuit is created using a capacitor, an inductor, a rectifier and the battery being recharged. The rectifier and battery combine to create circuitry that is equivalent to an AC component. The equivalent circuitry is in series with the inductor. The capacitor is in parallel with the inductor and equivalent circuitry. The resultant circuit is tuned and can be operated at a resonance frequency. In operation, the tuned circuit provides a recharging current to the battery without the need for a transformer or current resistive elements. The result is a recharging system and circuit that is smaller, lighter and far more power efficient than prior art battery chargers.

1. A circuit for recharging a battery from an AC power source, comprising:
a capacitor; an inductor; a rectifier; wherein said inductor and said rectifier and said battery form a series combination; wherein said capacitor is in parallel with said series combination; and wherein said capacitor, said inductor, said rectifier and said battery form a tuned circuit that resonates at a resonance frequency, and wherein said tuned circuit produces a resonating current at said resonance frequency that is greater than current being drawn from said AC power source.
