@@@@Based on the working principle of the fly-back switching power supply, the paper works out the design steps for transformer discontinuous mode, derivates and progresses the formula of important parameters. Simultaneously, the paper also calculates the parameters of primary and secondary voltage and current which have a certain value for the selection of the components of the switching power supply. Using development tools of Labview and Matlab to program the design of transformer. The results prove that the designed transformer for the switching power supply in the BLDCM control system has low ripple under full load and has stable performance.
