Analysis of a Pulsed Power System Containing Rotating Machine

Abstract

Several hundred megajoules of energy lasting for several seconds are required for magnetic fusion experiments. Such high energy can be stored as inertial energy in an alternator which is brought up to speed slowly. The alternator is then discharged through a thyristor converter to magnets which produce sustain the plasma. A major portion of the inertial stored energy, for reversed field pinch experiments in Los Alamos, will be dissipated in charging the magnetizing coil to produce the plasma. The plasma is then sustained, during the flat-top period, by energizing the magnetizing coil in the reverse direction. To hold the plasma current constant at the required level, the output voltage of the converter must be held at a prescribed level by controlling the firing angle of the thyristors. The paper discusses the possibility of using the same converter for both the magnetizing and the flat-top periods. It also analyzes the electrical requirements that will be imposed on the alternator and the converter.
