摘要： PURPOSE:To compensate effectively the unbalance of supply current among the plurality of power sources and to prevent the biased life of a product from being shortened by lowering an overcurrent detecting point of each power device according to the increase in number of the power sources to be amounted for reducing the degree of unbalance of supply current among the power sources. CONSTITUTION:Supposed that there is only one power circuit, a power supply at an overcurrent detecting point when only one power circuit is mounted I01 is expressed by the formula I (R1, R2, RS; resistance, Er; reference voltage source). When the second power circuit is mounted and a resistor R2 of the second power circuit is connected in parallel with the R2 of the first power circuit, a power supply at an overcurrent detecting point when two power circuits are mounted I02 is expressed by the formula II and is nearly 1/2 of the I01. The total power supply of the two power circuits is I0. This means that the overcurrent detecting point can be adjusted automatically only by mounting the power circuits after a difference in current between the two power circuits is reduced. Consequently, the life of each power supply can be effectively extended when the power supplies are operated in parallel with each other.

摘要： PURPOSE:To reduce cost through mass production by controlling the output voltage of a switching power supply according to the fluctuation of current or power to be fed from a fuel cell DC parallel operating system to a load or the fluctuation of output voltage from a rectifier thereby integrating the type of DC power supply constituting a fuel cell power supply. CONSTITUTION:Outputs from a fuel cell power supply 30 and a rectifier 5 are connected in parallel so that a commercial power supply 4 shares the output current or power to a load exceeding the rating capacity of a fuel cell power supply 30. Sharing rate between the fuel cell power supply 30 and a rectifier 5(commercial power supply 4) is controlled by varying the output voltages from main circuits 21-1, 22-1 of a switching power supply through constant output voltage control circuits 21-2, 22-2. According to the constitution, fuel cell power supply requiring high installation cost can be operated at rated capacity or thereabout resulting in effective utilization thereof.
