請(qǐng)問(wèn)Flyback初級(jí)電流何時(shí)進(jìn)入DCM?
請(qǐng)問(wèn)各位大俠,
隔離Flyback初級(jí)的電流在輸出最大電流Iomax的百分之多少時(shí)進(jìn)入DCM比較合適?
也就是說(shuō)何時(shí)可以得到比較理想的效率?
有的說(shuō)50%時(shí)效率比較好,
有的說(shuō)滿載時(shí)進(jìn)入CCM效率比較好,
請(qǐng)問(wèn)實(shí)際中有沒(méi)有比較優(yōu)化的參數(shù)?
還是說(shuō)根據(jù)不同的輸出功率或者其它參數(shù)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.
