The Tokamak Fusion Test Reactor has several large coils designated for plasma initiation, confinement, heating, and position control. The coils are supplied by high current pulses with an approximate duration of 10 sec and a repetition period of 5 minutes. The peak power of the pulses is approximately 900 MW with an average power of 30 MW. This paper describes the engineering problems related to the experimental reactor and discusses the flywheel generator energy storage system, the developed rectifier/inverter arrangement, and an operational method which minimizes the reactive power consumption and insures the safe dissipation of magnetic energy in case of a fault. In addition, the switching problem related to the required swing of large current in the ohmic heating coils is analyzed.
