PROBLEM TO BE SOLVED: To provide a power mixing load distribution circuit of simplified structure which can combine a plurality of power sources with a low loss and can distribute change of load to a plurality of power sources. SOLUTION: A plurality of transistors in which bases and collectors are connected in common, a bias resistor connected between the common base and collectors of a plurality of transistors, and a plurality of resistors connected respectively to the emitters of a plurality of transistors are comprised. A plurality of resistors are connected to a plurality of DC power sources of the same polarity and the common collectors of a plurality of transistors are connected to a load. A plurality of power sources are combined in a lower loss with a transistor providing a small voltage drop. Moreover, when a differential circuit is formed of a plurality of transistors and a current flowing into a transistor increases, such increase is controlled and a current flowing into the other transistor increases, and increase of a load current can be distributed to a plurality of power sources. |
