AC operation with multiple full cycles has been successfully performed on the su-perconducting tokamak HT-7.In the experiment,it was discovered that the saturation of thetransformer magnetic flux with DEF,a signal name,was one of key aspects that affected the ACoperation.The conditions of DEF were examined through the DEF feedback control system.Bycontrolling the working patterns of the subsystems,namely the poloidal field control system anddensity control system,it was guaranteed that DEF would remain in the non-saturated status.
