Design of single-ended flyback transformers of switching power supply

Transformer is the cores of the switching power supply devices.In the design of flyback transformers that worked in the current continuous and current discontinuous mode had many issues such as many formula and parameters of design and so on.This paper carefully analyzed various factors include that the core size,the original edge inductance value,air-gap size,the original edge of the coil turns,and the diameter of the coupling winding around the law and other issues.It provided the concrete method and procedures about the design of flyback transformers.By means of practical examples of design,it has been proved that this method can rapidly design flyback transformers as needed.
