The toroidal field power supply of HL-2A Tokamak operated in pulse mode is fed by two sets of motor generators with corresponding diode rectifiers. Each six-phase generator has two star stator windings with a phase difference of 30o between them. In this paper, the model of six-phase generator with rectifier load is built and toroidal field discharge operated in pulse mode is simulated based on dual DQ0 transformation.
