Abstract

PURPOSE:To obtain a highly reliable power source by a method wherein an electric power is supplied to a computer system by either one of a plurality of uniterruptible power supplies and the other units are kept in waiting condition while the power supply to the computer system is switched to the other waiting power units only when the AC output of the supplying power unit is stopped. CONSTITUTION:Uninterruptible power supplies 4, 5 receive electricity from a commercial power source 1 and convert it into a specified AC output to supply it to a computer system 3. During the operation of the uninterruptible power supply 4, a relay control unit 9 excites a relay 6 by detecting the output of the uninterruptible power supply 4 to supply electric power to the computer system 3 and a control unit 8. During the operation of the uninterruptible power supply 5, the control unit 8 operates another relay 7 to check to the operation of the uninterruptible power supply 5 upon normal power supply of the commercial power source and a service interruption. If the service interruption is caused when the uninterruptible power supply 4 is faulty, the relays 6, 7 are put OFF and back-up operation may be effected by the uninterruptible power supply 5.
