Abstract

A circuit for charging a storage battery (10) at constant current by means of a transformer (T) whose primary winding (12) is connected to an AC mains (11) and whose secondary winding (13) feeds a rectifier bridge (14). The storage battery is connected, at the output of the rectifier bridge, in series with a resistor (15) and a light bulb (16). A transistor (18) has its emitter-collector circuit connected in series with a resistor (19) and this series connection is connected in parallel with the light bulb (11). The transistor base is biased by a voltage divider chain (20, 21) connected between one pole of the battery and the output of the rectifier bridge. While the bulb is in order it acts both as a pilot lamp and as a regulator device to ensure substantially constant current charging of the battery. The transistor is then off. If the bulb filament breaks, the transistor is biassed to become conductor to maintain adequate charging current through the battery.
