摘　　要：根据设计全数字永磁交流伺服系统的需要,使用Power Integration公司生产的开关电源专用集成芯片TOP224Y,设计了单端反激式多输出辅助开关电源。使用该芯片设计的小功率开关电源,可大大减少外围电路,降低成本,提高可靠性,同时,可以改善电源的电磁兼容性能。重点论述了开关电源的电路设计及高频变压器的设计。本辅助电源稍经改动也可以直接用在其他电机控制系统中。TOP224Y intergrated circuits are produced especially for switching power supply by Power Integration Company, which is used to design flyback switching power for full-digital PMSM servo system. Designing low power switching power supply with such integrated circuits can decrease parts count and cost, increase reliability, but also can improve the EMC characteristics. The switching power circuit design and high-frequency transformer design are mainly described. This switching power is also used to other motor control system.
