摘要
A detection circuit for detecting the voltage between phases of a polyphase alternator for the purpose of controlling the putting into operation of a regulator for regulating the charging of a motor vehicle battery by said alternator, the circuit comprising differential discrimination means for the amplitude of the voltage between a pair of phase signals delivered by the alternator. The differential discrimination means comprise a pair of transistors each constituting means for comparing the inter-phase voltage with a threshold voltage defined by its emitter-base junction voltage, said threshold voltages being of small magnitude and of opposite polarity with respect to each other.
