PURPOSE:To suppress fluctuation of output voltage, by maintaining the voltage appearing at the output terminal of a duplex power source equipment at a predetermined level through function of a feedback voltage regulating section. CONSTITUTION:A voltages from original power sources 4, 4a are regulated through feedback voltage regulating sections 7, 7a to predetermined levels and outputted. Control sections 13, 13a provide first and second drive signals corresponding to the modes of a faulty state signal and a counterpart state signal, then provides a self state signal corresponding to both signals. The self state signals are fed to the control sections 13, 13a and the first or second drive signal is used for controlling first to third switches 23, 23a, 24, 24a, 25, 25a. First switches 23, 23a are arranged between the output terminals of the voltage regulating sections 7, 7a and the output terminals 12, 12a of the equipment while the second switches 24, 24a are arranged between the feedback terminals of the voltage regulating sections 7, 7a and the output terminals 12, 12a of the equipment and the third switches 25, 25a are arranged between the output terminals of the voltage regulating sections 7, 7a and the feedback terminals. |
