计算开关电源变压器的参数，根据输入的功率、工作频率等，可可以自动计算出磁芯尺寸和线圈圈数等，已通过测试。 -Calculate the parameters of the switching power supply transformer, according to the input power, operating frequency, can automatically calculate the core size and the number of turns have pass

线径的计算： 一般铜线截面积每平方mm取值5安培电流。（高频取4.95，低频取3.5.）(Calculation of wire diameter: The average copper wire section is 5 amperes per square mm. (high frequency takes 4.95, low frequency takes 3.5.))

该资料给出了开关电源高频变压器的计算方法(The calculation method of high-frequency transformer for switching power supply is given.)
