Abstract：
 This invention relates to a super-conductive current control technology for the current flows through a super-conduction coil when storing energies characterizing that this invention converts a power supply three phase voltage, a load three-phone voltage to ordered stable control current on the d, q shaft by a DSP chip, then converts the ordered current to six control pulses by a current vector pulse width regulator to send them to the grids of transistors in a current transformer composed of correspondingly serial connected six insulation grating bi-polar transistors and six diodes, the input of the current transformer is three-phase load voltage added on three central points of three arms, the output is the super-conduction current flowing through the super-conduction coil connected between the negatives of the three diodes at the end of the three arms and the source of the bi-polar transistor at the start end.
