V或220 V左右，中小功率高壓電源選單相供電，大功率高壓電源選三相供電。另一部分是低壓直流供電，主要供高壓電源的控制部分使用，如±5 V、±15 V、±27 V等等．一般電流較小，功率不高。在實(shí)際的系統(tǒng)中，高壓電源從系統(tǒng)獲得供電，交流供電提供功率來源，低壓直流供電提供控制使用。而系統(tǒng)為接地安全起見，通常將數(shù)字地、模擬地、線纜屏蔽層和機(jī)殼大地相連，甚至有些低壓直流供電的回線與屏蔽層或大地直接相連。高壓電源的PWM控制部分要與高壓反饋電壓作比較，所需低壓直流供電常常需要單獨(dú)供電，為隔離起見其回線不能接地。這樣，系統(tǒng)低壓直流供電在這種情況下不能滿足要求，高壓電源無法使用系統(tǒng)的該路供電，而必須在高壓電源內(nèi)使用適當(dāng)DC／DC模塊電源生成所需的隔離低壓直流供電電源。</p><p

電壓轉(zhuǎn)換為手機(jī)本身的適當(dāng)電壓，這樣可以確保一個(gè)平穩(wěn)的電壓流為鋰離子電池充電，電源模塊也是這個(gè)變流技術(shù)設(shè)備的本質(zhì)。模塊稱為負(fù)載點(diǎn) 電源供應(yīng)系統(tǒng)或使用點(diǎn)電源供應(yīng)系統(tǒng)。</p><div
