Design and development of the power supply system for HL-2A tokamak

HL-2A tokamak operation needs several pulse DC power supplies with peak power of 300 MVA and the energy content of 1200 MJ per shot. To meet this requirement, three flywheel motor-generators (MG) are used, and the diode and thyristor AC/DC converters are developed to power the HL-2A toroidal and poloidal field coils. A new control system of the power supply is implemented. The power supply system is put into operation. The design and development of this power supply system are presented.
