Abstract

PURPOSE: To limit the maximum current value of a DC power supply unit within the maximum allowable standards, by feeding back a maximum current feedback signal through a diode and setting the constants of a current limit circuit so that the feedback signal can balance with maximum limit value of a current reference signal.
CONSTITUTION: DC power supply units 1 and 2 are connected in parallel at DC side, respective output current is detected 14, 15, and a current reference signal 18 is obtained corresponding to the deviation between each output voltage of the units 1, 2 and the specified reference input signal at a control circuit 12. In the circuit 12, if specified amount or more unbalancing is produced to the current between the units 1 and 2, the maximum current detecting signal is fed back through a diode D and the constants are set so that it can be balanced with the maximum limit value of the current reference signal 18. Thus, the output of the circuit 12 can limit the maximum current value of the units 1 and 2 within the maximum rating.
