PURPOSE:To provide a power source to be coped with by detecting and controlling characteristic change of a DC generator having inherent characteristics of a fuel cell, etc. CONSTITUTION:The power source comprises a main circuit and controller 3, an output error voltage amplifier B for comparing an output detection voltage Vos proportional to an output current of the controller 3 with a reference output voltage Vor to amplify and supply its differential voltage to the controller 3, an input error voltage amplifier C for comparing an input detection voltage Vis of the controller 3 with a reference input voltage Vir, and a reference output voltage controller D for varying the voltage Vor when the voltage Vis is lower than the voltage Vir. |
