Battery charger

Patent ·
OSTI ID:6063808
;
A battery charger can charge a battery from a primary power source having a peak voltage exceeding the maximum battery voltage independently producible by the battery. The charger has output terminals, a switch and a feedback circuit. The output terminals are adapted for connection to the battery. The switch can periodically couple the primary power source to the output terminals to raise their voltage above the maximum battery voltage. The feedback device is responsive to the charging occuring at the terminals for limiting the current thereto by varying the duty cycle of the switch.
