Abstract

Thailand Tokamak-1 is a small size tokamak, formerly known as HT-6M and belong to Institute of Plasma Physics, Chinese Academy of Science (ASIPP, China). The HT-6M was donated to Thailand Institute of Nuclear Technology (TINT, Thailand) and will undergo a reconstruction in order to re-commission again. For the reconstruction of power supply for magnet systems, three circuits have been designed based on capacitor discharge for the toroidal field magnet coil, the heating field magnet coils, and the vertical field magnet coils. With a simulation of new circuit design, the TT-1 will have toroidal magnet field about 1.5 T for a flattop duration of 100 ms with Ohmic heating and vertical magnetic field of the same duration.
