초록 ▼

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 battieries.

대표청구항 ▼

An improved DC power network comprising: (a) a series connected pair of batteries; (b) an electrical generator connected across said series pair; (c) an equalizer circuit for equalizing the voltages of said batteries and comprising a regulated DC/DC converter for converting electrical energy to the voltage of a first one of said batteries from the sum of the voltages of said batteries, said converter having its input connected across said pair of batteries and its output connected to said first battery, the regulator circuit of said converter including a voltage dividing circuit connected across said pair of batteries to provide the regulator with its reference voltage equal to the product of the ratio of the desired voltage of said first battery to the sum of the desired voltages of each of said batteries multiplied by the sum of the actual voltages of said batteries; (d) a load connectable across said series pair; and (e) a load connectable across said first battery.
