Abstract:
A system for regulating an alternator charging system comprising:a programmable memory for storing the regulating voltages used at specific temperatures for the specific alternator charging system requirements of an alternator and generating a data signal indicative of the regulating voltage; a circuit for generating a digital signal indicative of both the temperature of a battery supplied by the alternator charging system and the charging system voltage and comprising an n-bit latch circuit for receiving digitally multiplexed data representative of the temperature and charging system voltage and outputting latched signals, one of said latched signals being input to said memory; and a digital comparator for receiving a latched signal from said n-bit latch circuit and data signal from said memory and comparing the latched signal with the data signal indicative of the regulating voltage stored within the memory for the specific temperature indicative of the temperature of the battery supplied by the alternator charging system and generating a regulator control signal.
