According to the needs of the Novel Linear Motor Transport System, a new kind of switching power supply is designed,which contains a two-stage step-down structure. The paper presents the structure of the main circuit, the process of device selection, the control system and strategy,＇ the protection logic,the simulation model and also the solution against the problem of short-time power failure. The result of the experiments showed that the switching power supply has good performance and stability which fully meet the requirements of the New Linear Motor Transport System.
