Abstract

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.
