[問題]CCM DC converter需要no saturation core
最近看DC converter的資料 其中一段如下
The inductor current contains an ac component which is independent of the dc
load current in CCM and a dc component which is equal to the dc load current IO.
As the dc output current IO flows through the inductor L, only one-half of the B –H
curve of the inductor ferrite core is exploited. Therefore, the inductor L should be
designed such that the core will not saturate. To avoid core saturation, a core with an air gap
and a sufficiently large volume may be required
其中紅字一段是我比較不了解的地方 請教板友這方面的原理以及參考資料 謝謝
