Abstract
PURPOSE:To decrease the number of the monitor circuits by installing the monitor circuit to the output final step. CONSTITUTION:Directional coupler 25 is provided to final output terminal 27, and thus the output signals are detected to monitor the system. In case some fault is detected, switch controller 27 switches first using/stand-by system 11. And if the output is abnormal yet, the switching is given to the using/stand-by system of the next step. As a result, the installation of the fault detector circuit will do just at one area in the system containing the using/stand-by switching system featuring the vertical system.
