Circuit Analyses of the Filament Ion Source Power Supplies for the ITER Neutral Beam Test Facility

This paper describes circuit simulations of the filament heating circuit for the neutral beam test facility of the international thermonuclear experimental reactor (ITER). The novel features of ITER filament heating circuit are studied both in normal operation and under fault conditions. The proposed scheme is found capable of performing as required and results are illustrated useful for further detailing of the design
