開關電源功率20w  Fs=72kHz Vmos=800v Vout=12v
Vin=85-265v AC
變壓器參數(shù)如下
磁芯              EE22             ee20
初級電感         1.375mH           1.375mH
Np             167                105
Ns              8                  5
Nf              8                  5
氣息              0.62mm            0.4mm
請問上面參數(shù)有問題嗎?
還有就是線徑應是多少
