Abstract

PURPOSE:To prevent the fluctuation of coil current for a polaidal power supply circuit of an experimental equipment for nuclear fusion, by connecting a dummy load corresponding to a thyristor and a forcible commutation switch which cuts off the current flowing to the dummy load to the DC output side of the thyristor. CONSTITUTION:A capacitor 6 is charged to the polarity shown in the diagram, and at the same time a forcible commutation switch 9 is turned on to conduct electricity to a dummy load 8 from a thyristor rectifier 2. Then a switch 5 is applied to give a rise to a coil 7. Then the switch 9 is turned off when a coil current ic has its change factor which is equal to the current of the load 8 within a range of a positive level or zero. Thus the current so far flowing to the load 8 is supplied to the coil 7 as well as to capacitor circuits 4-6. Thus it is possible to reduce the fluctuation of coil current when the capacitor 6 is switched to the rectifier 2.
