在電源供給的電壓升高時(shí)，能把部分能量儲(chǔ)存起來，而當(dāng)電源電壓降低時(shí)，就把能量 釋放出來，使負(fù)載電壓比較平滑，即電容 C 具有平波的作用；與負(fù)載串聯(lián)的電感 L,當(dāng)電源供給的電流增加（由電源電壓增加引起）時(shí)，它把能量儲(chǔ)存起來，而當(dāng)電流減小時(shí)，又把能量釋放出來，使負(fù)載電流比較平滑，即電感 L 也有平波作用。另外 5509的通用 I/O 引腳 XF 設(shè)計(jì)測試指示燈，可通過軟件設(shè)置用來適時(shí)觀察系統(tǒng)的狀態(tài)，如圖所示。 （ 4）
