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 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.255.11.207

我想是在說 BH CURVE 是13象限 只用到第一象限
