Power and capacity reduction scheme for tokamak poloidal field power supply using superconducting coils

A new-type poloidal field coil power supply for future tokamak reactors, aimed at removing the disturbance to the utility power system and reducing the power supply capacity, is proposed. PF power supply requires reductions of the capacity and the enormous regenerative power, by introducing a superconducting coil to the power supply. The new scheme of the circuit is described. After analyzing the start-up scenario of ITER, the concept of the new system by experiments are demonstrated
