Patent
·
OSTI ID:5583147
A lightweight, efficient, transformerless battery-charging system especially for use with electric vehicles, wherein a switching regulator stores only a fraction of the energy in each charging pulse, and much of the charging energy is supplied directly from the powerline and never stored in the charger. Major components include an overload and ground-fault protective current interruptor, an rf interference filter and line rectifier , and a switching regulator capable of maintaining a constantcurrent constant-voltage output, providing controlled input current throughout the ac cycle and including means for external shutdown.
