Power supplies for plasma column control in COMPASS tokamak

Popis výsledku v původním jazyce

The main magnetic fields in COMPASS ? i.e. The Toroidal, Magnetising, Equilibrium, and Shaping Fields ? are created by a set of four corresponding thyristor power supplies controlled in a 0.5 ms loop.The plasma position has to be controlled both radiallyand vertically by two additional magnetic fields provided by two fast amplifiers (FAs) based on MOSFET technology, each supplying 100 V and up to 5 kA.Currently, an ongoing project aims at ELM triggering by fast changes of the vertical position of the plasma column, also referred to as vertical kicks. For this purpose, a new Vertical Kicks Power Supply (VKPS) capable of quick change of vertical plasma position is being constructed. This power supply should operate at up to 1.2 kV with switching frequency up to 5 kHz. It is designed as a H-bridge but based on IGBT transistors which can be operated at higher voltages than MOSFETs.We focus on the FAs and VKPS engineering design and required output parameters.
