| Abstract: | This paper presents the design process of a switching mode power supply（SMPS） with multiple isolated out- puts based on TOP247Y. The basic principle of SMPS is presented and a method for transformer design by using PI transformer designer software is given. After the total design of the SMPS a prototype is developed, which has simple structure and is easy to operate. Finally, results show that the SMPS has a number of advantages such as good dynamic performace and high stability. It can be used as the special driving power supply for IPM and other. An efficient, fast, flexible design for power supply is provided in this paper. |
