摘　　要：文章针对开关电源变压器设计中存在公式繁多,参数计算困难等问题,提出了一种简单实用的设计方法。该方法统一了变压器工作在电流连续模式和断续模式下的计算公式,有效解决了原边电感值、线圈匝数、线径、磁芯大小等参数的设计,降低了设计难度,提高了设计效率,并给出了设计实例。The paper puts forward a simple and practical design method for there are many issues such as various formulas,parameter calculation difficulty in switching power supply transformer. This method unified the formulas of current continuous mode and current discontinuous mode,effectively solved the original side inductance value,the number of coil turns,wire diameter,core size and so on,reduced the design difficulty,improved the design efficiency and finally gave a design example.
