按照開(kāi)關(guān)管的開(kāi)關(guān)條件，DC/DC轉(zhuǎn)換器又可以分為硬開(kāi)關(guān)（HardSwitching）開(kāi)關(guān)電源開(kāi)關(guān)電源和軟開(kāi)關(guān)（SoftSwitching）兩種。硬開(kāi)關(guān)DC/DC轉(zhuǎn)換器的開(kāi)關(guān)器件是在承受電壓或流過(guò)電流的情況下，開(kāi)通或關(guān)斷電路的，因此在開(kāi)通或關(guān)斷過(guò)程中將會(huì)產(chǎn)生較大的交疊損耗，即所謂的開(kāi)關(guān)損耗（Switchingloss）。當(dāng)轉(zhuǎn)換器的工作狀態(tài)一定時(shí)開(kāi)關(guān)損耗也是一定的，而且開(kāi)關(guān)頻率越高，開(kāi)關(guān)損耗越大，同時(shí)在開(kāi)關(guān)過(guò)程中還會(huì)激起電路分布電感和寄生電容的振蕩，帶來(lái)附加損耗，因此，硬開(kāi)關(guān)DC/DC轉(zhuǎn)換器的開(kāi)關(guān)頻率不能太高。軟開(kāi)關(guān)DC/DC轉(zhuǎn)換器的開(kāi)關(guān)管，在開(kāi)通或關(guān)斷過(guò)程中，或是加于其上的電壓為零，即零電壓開(kāi)關(guān)（Zero-Voltage-Switching。

吸合電流吸合電流是指繼電器能夠產(chǎn)生吸合動(dòng)作的電流。在正常使用時(shí)，給定的電流必須略大于吸合電流，這樣繼電器才能穩(wěn)定地工作。而對(duì)于線(xiàn)圈所加的工作電壓，一般不要超過(guò)額定工作電壓的1.5倍，否則會(huì)產(chǎn)生較大的電流而把線(xiàn)圈燒毀。釋放電流釋放電流是指繼電器產(chǎn)生釋放動(dòng)作的電流。當(dāng)繼電器吸合狀態(tài)的電流減小到一定程度時(shí)，繼電器就會(huì)恢復(fù)到未通電的釋放狀態(tài)。這時(shí)的電流遠(yuǎn)遠(yuǎn)小于吸合電流。電壓電流觸點(diǎn)切換電壓和電流是指繼電器允許加載的電壓和電流。它決定了繼電器能控制電壓和電流的大小，使用時(shí)不能超過(guò)此值，否則很容易損壞繼電器的觸點(diǎn)。觸點(diǎn)性能a．動(dòng)合主觸點(diǎn)性能動(dòng)合主觸點(diǎn)在電壓不大于250V時(shí)，能接通直流或交流5A，但是斷開(kāi)它所接通的電路。

如市電電源或蓄電池電源，轉(zhuǎn)換成滿(mǎn)足設(shè)備要求的質(zhì)量較高的直流電壓（精電）。直流開(kāi)關(guān)電源的核心是DC/DC轉(zhuǎn)換器。因此直流開(kāi)關(guān)電源的分類(lèi)是依賴(lài)DC/DC轉(zhuǎn)換器分類(lèi)的。也就是說(shuō)，直流開(kāi)關(guān)電源的分類(lèi)與DC/DC轉(zhuǎn)換器的分類(lèi)是基本相同的，DC/DC轉(zhuǎn)換器的分類(lèi)基本上就是直流開(kāi)關(guān)電源的分類(lèi)。直流DC/DC轉(zhuǎn)換器按輸入與輸出之間是否有電氣隔離可以分為兩類(lèi)：一類(lèi)是有隔離的稱(chēng)為隔離式DC/DC轉(zhuǎn)換器；另一類(lèi)是沒(méi)有隔離的稱(chēng)為非隔離式DC/DC轉(zhuǎn)換器。隔離式DC/DC轉(zhuǎn)換器也可以按有源功率器件的個(gè)數(shù)來(lái)分類(lèi)。單管的DC/DC轉(zhuǎn)換器有正激式（Forward）和反激式（Flyback）兩種。雙管DC/DC轉(zhuǎn)換器有雙管正激式（DoubleTransistorForwardConverter）。
