Abstract
The DC component of short-circuit current in high power test affects di/dt and TRV at zero crossing point,and the quality and efficiency of the test depend on accurate control of the DC component.In the high power test,three separate switches are used for phase-selection closing to obtain the required short-circuit current.In this paper,the phase selection methods for respectively generating the fully symmetrical and the maximum asymmetrical short-circuit current are obtained through theory analysis,and the method for setting closing time series according to current waveform is summarized.Besides,a circuit containing Y/△ transformer is analyzed.关键词
