ABSTRACT:
A feeder circuit for the rapid shutdown for safety devices in nuclear reactors comprising a controllable rectifier providing a d.c. output from an a.c. input of network frequency; a number of inverters to invert said d.c. output to an alternating current at a frequency higher than that of the network and to elevate the voltage thereof; and an adder to add the currents exiting from such inverters and rectify the current sum. The exit voltages of the inverters are dephased with respect to each other by 180
, n being the number of the inverters in the feeder.
