Battery charger and power supply circuitry

Patent ·
OSTI ID:5388760

A transformerless battery charging circuit is described including a rectifier, a semiconductor switch in series with the battery, a sensing network monitoring battery voltage, a trigger circuit responsive to the sensed battery voltage for controlling operation of the semiconductor switch, and a voltage regulator for regulating output voltage of the rectifier as supplied to the triggering and battery voltage sensing networks. The circuitry in combination with an appropriate rechargeable battery also serves as a power supply to drive a dc load connected to the battery.
