自耦（變比）調(diào)整型

1、機(jī)械調(diào)壓型，即以伺服電機(jī)帶動(dòng)炭刷在自耦變壓器的的繞組滑動(dòng)面上移動(dòng)，改變Vo對(duì)Vi的比值，以實(shí)現(xiàn)輸出電壓的調(diào)整和穩(wěn)定。該種穩(wěn)壓器可以從幾百瓦到幾千瓦。它的特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，造價(jià)低，輸出波形失真??；但由于炭刷滑動(dòng)接點(diǎn)易產(chǎn)生電火花，造成電刷損壞以至燒毀而失效；且電壓調(diào)整速度慢。

單靠水位高低之差不能維持穩(wěn)恒的水流，而借助于水泵持續(xù)地把水由低處送往高處就能維持一定的水位差而形成穩(wěn)恒的水流。與此類似，單靠電荷所產(chǎn)生的靜電場(chǎng)不能維持穩(wěn)恒的電流，而借助于直流電源，就可以利用非靜電作用（簡(jiǎn)稱為“非靜電力”）使正電荷由電位較低的負(fù)極處經(jīng)電源內(nèi)部返回到電位較高的正極處，以維持兩個(gè)電極之間的電位差，從而形成穩(wěn)恒的電流。因此，直流電源是一種能量轉(zhuǎn)換裝置，它把其他形式的能量轉(zhuǎn)換為電能供給電路，以維持電流的穩(wěn)恒流動(dòng)。
