PURPOSE:To facilitate temperature compensation of an output current in an output current balancing constant voltage power source which performs parallel operation current control. CONSTITUTION:By using a thermosensitive resistor for the resistor 1 or 2 being connected by a current feedback circuit 3, the current feedback signal being given to a pulse control circuit 5 by temperature is increased or decreased, and the temperature compensation to the balancing of the output current is sought. In the parallel operation of a plurality of output current balancing constant voltage power source, the inequality of the output currents caused with the temperature difference between respective power sources is prevented and also the reliability is improved. |
