<p>PROBLEM TO BE SOLVED: To obtain a power supply system in which stability and reliability of power supply are enhanced using simple configuration and control.SOLUTION: A power supply system is made redundant by using a plurality of power supply units, which are operated at a time ratio set so as not to overlap in a predetermined redundant period, and while switching the output sequentially, a required power is supplied continuously to a load. Upon occurrence of output abnormality in any power supply unit, power supply to the load is substituted instantaneously with no interruption by a backup circuit using a capacitor, in the period of a time ratio set in the power supply unit the output of which is abnormal, and the time ratio is reset for each power supply unit in the immediately following redundant period.</p> |
