ABSTRACT:
An apparatus and method for recharging a battery. The invention includes modulating a rail voltage with a modulation signal that oscillates at a radio frequency, preferably at a frequency that matches the natural resonant frequency of the battery. The modulated rail voltage is provided to the battery to recharge the device. The apparatus may have a follower circuit which shifts the modulation frequency to follow any change in the natural resonant frequency of the battery.
