PURPOSE:To effect current balancing operation among normal power source devices by a method wherein the connection of an own output current signal to a current balancing terminal is opened when an own output current is smaller than that of other power source device while said connection is closed only when the own output current is larger than that of other power source device. CONSTITUTION:An amplifier A1 and a diode D2 form an ideal diode and is energized when an its output current is larger than the output current of another power unit to make a voltage impressed on the non-conversion and conversion input terminals of an amplifier A2 zero volt. On the contrary, when its output current is smaller than that of another power unit, an ideal diode circuit is cut off to generate a voltage between the input terminals of the amplifier A2 and operate it whereby the reference voltage of a voltage stabilizing circuit is increased to operate the circuit so as to increase the output current of the same. According to this operation, the output currents of respective power units are balanced. |
