Study On Soft-starting Of Motor With High Voltage

This paper put the emphasis on the application of power electronics mode on the soft-starting of motor with high voltage on the basis of the analysis of all soft-starting modes. In order to enhance the voltage degree of soft starter, the paper apply the series connection of thyristor to soft-starting of motor and solve the static and active voltage balancing through the tested voltage balancing circuit and the paper simulated the electromagnetic field around the conductor of main-circuit by ANSYS and make a reference for layout of control circuit.lt designed the pulse-triggering model based on FPGA and driving circuit and made a test though the experimental circuit. The result of experiment has validated the correctness of the design and research in this paper and made a reference for the utility.
