請問Flyback初級電流何時進入DCM?
請問各位大俠,
隔離Flyback初級的電流在輸出最大電流Iomax的百分之多少時進入DCM比較合適?
也就是說何時可以得到比較理想的效率?
有的說50%時效率比較好,
有的說滿載時進入CCM效率比較好,
請問實際中有沒有比較優化的參數?
還是說根據不同的輸出功率或者其它參數有不同的選擇?
謝謝!

I think maybe what your question is not correct.
We want the power supply has a possible high efficiency,But if the power supply have a high efficiency at light load,but the transformer get saturated during full load,that is not acceptable.
I think :
1:it is necessary that the transformer will never be saturated under any load and input condition(that include overload,unless your power supply has a very sensitive current detection function;)
2:At full load,the unit have possible high efficiency.
