ABSTRACT:
In a power source system for supplying a load with a load voltage and a load current, a plurality of power sources share the load at rates of load sharing and have negative resistance characteristics. When the power sources are connected together in series, the rates are determined by source voltages produced by the respective power sources which also produce d.c. currents. Each d.c. current increases with an increment of each rate so as to specify each negative resistance characteristic. A control circuit is included in each power source to control the d.c. current and may be a combination of a current detector (60a, 60b) and a resistor (56a, 56b). Alternatively, the rates are determined by source currents produced by the respective power sources which also produce d.c. voltages when the power sources are connected together in parallel. The d.c. voltages are controlled by control circuits to specify the negative resistance characteristics so that each d.c. voltage increases with an increment of each source current. Each negative resistance characteristic may be changed to a positive resistance characteristic at a preselected one of each rate.
