Abstract

1,084,087. Automatic voltage control. NOVI - P.B. April 5, 1966 [April 6, 1965], No. 14993/66. Heading G3R. A charging circuit for a battery B comprises an alternator-rectifier bridge arrangement generally similar to that described in Specification 969,691, and a control circuit to determine the firing instants of the rectifiers T1, T2, T3 consisting of an NPN transistor connected between the negative terminal of the battery and the common point of the protective resistors R1 --- R4, the conductivity of the transistor being controlled by a voltage divider P1, P2, R5, R6 connected across the battery and feeding the transistor base through Zener diodes Z1, Z2. Bridge members T1, T2, T3 and D1, D2, D3 may be interchanged, in which case a PNP transistor is used with its emitter connected to the positive terminal of the battery, and diodes Z1, Z2, D4, D5, D6 are reversed, Fig.2 (not shown). Diode Z1 acts as a non-linear impedance and may be replaced by a voltagedependent resistor in series with the diode Z2 between the transistor base and a single tapping on the voltage divider, Fig. 3 (not shown). The non-linear component may be in the transistor collector circuit instead of the base.
