摘要： PROBLEM TO BE SOLVED: To provide a controller for a power supply apparatus, which simply suppresses the fluctuation of output frequencies caused by frequency droop characteristics without determining an operating state nor a transverse current amount or without using a detection circuit of the output frequency nor a frequency controller when a plurality of power supply apparatuses are connected in parallel using frequency droop characteristics. SOLUTION: The controller for the power supply apparatus supplying an alternating current to a load is provided with: a phase adjuster 3 for adjusting the phase of own output voltage in accordance with the effective portion of the own output power or output current of the power supply apparatus. It is further provided with an amplitude adjuster 5 for adjusting the amount of the output of the phase adjuster 3, a subtractor 6 for reducing the output of the amplitude adjuster 5 from the difference between the reference value of the effective portion and the actual value of the own output power of the power supply apparatus, and an adder 2 for adding the output of the phase adjuster 3 to the reference phase of the output voltage. The output of the subtractor 6 is input into the phase adjuster 3. COPYRIGHT: (C)2009,JPO&INPIT
