Title: DC power system having battery voltage equalizer circuit

Abstract

An equalizer circuit is disclosed for permitting two series 12 volt batteries to supply both 24 volts and 12 volts and which maintains the batteries charged to equal voltages. The equalizer circuit is a regulated DC to DC converter with its output connected across the 12 volt battery which is connected to 12 volt loads and its input connected across either the other battery or the 24 volts of the input series pair of batteries. The reference voltage for the regulator is derived from a voltage dividing circuit which is connected across the 24 volt terminals of the two batteries. The voltage dividing circuit provides a reference voltage which is equal to half the voltage across the sum of the voltages of the two batteries.
