Abstract

PURPOSE: To maintain the necessary electric power to be outputted, even in case when a fault has occurred partially, by providing an auxiliary unit amplifier at least, in addition to plural unit amplifiers.
CONSTITUTION: The switching controller 8 is connected to each input on-off switch 3 and each output on-off switch 5 through the on-off signal lines 9, 10, also is connected to the monitor terminal 12 of each unit amplifier 4 through the monitor signal line 11, and controls the switches 3, 5 so that the unit amplifiers 4 required for obtaining the necessary electric power are connected between the input electric power distributor 2 and the output electric power synthesizing device 6. When a fual has been detected in the unit amplifier which is being operated through the monitor signal line 11, the switching controller 8 detaches the faulty unit amplifier 4 from between the input electric power distributor 2 and the output electric power synthesizing device 6, and connects the auxiliary unit amplifier 4.1 between them.
