Abstract
At present, based on the features of Pulse Step Modulator (PSM) technology in high voltage power supply (HVPS) is applied to drive the auxiliary heating system in domestic and foreign Tokomak facility. Before design of PSM HVPS, it is necessary to consider the effect of stray parameter existed in HVPS on the dynamic process of HVPS and load. In this paper, based on PSM technology 50 kV HVPS have been completed which is built for EAST auxiliary heating system and the relationship between the stray capacitance and leakage impedance respectively existed in the oil isolation transformer and dry multi-secondary winding transformer is discussed. Finally a stray parameters electrical circuit model of HVPS is presented. At last, from the results of experiment,it is consistent with the results of simulation.
