Abstract:

The basic principle and realization steps of the HL-2A tokamak ohmic heating power supply running with- out circulating current are introduced in this paper. By means of the oretic analysis and simulation, a control scheme that can improve the inversion reliability of the positive thyristor rectifier is given. The control strategy that will be carried out when circulating current appears are discussed. The analysis is proven by the experiment results.

Key words: Ohmic heating power supply, Circulating current, Inversion running
