THE ARC POWER SUPPLY FOR THE TEXTOR NEUTRAL INJECTORS
The 24 single arcs in the plasma source of the TEXTOR neutral injector will be supplied with an overall current of 1800 A at an arc voltage of 150 V DC. The current should be switched on and off in less than 1 msec. The paper presents a new modular solution for such a power supply. Each arc is powered by a separately switched mode supply module. One single module consists of a diode rectifier bridge with a filter, a fast semiconductor switch, an inductance in series for stabilizing the current and a free wheeling path. The layout of this power supply system is described in detail based on test results. Design features and technical data are given.
