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。
2、改變抽頭型，將自耦變壓器做成多個(gè)固定抽頭，通過(guò)繼電器或可控硅（固態(tài)繼電器）做為開關(guān)器10件，自動(dòng)改變抽頭位置，從而實(shí)現(xiàn)輸出電壓的穩(wěn)定。
該種型穩(wěn)壓器優(yōu)點(diǎn)是電路簡(jiǎn)單，穩(wěn)壓范圍寬（130V-280V），效率高（≥95%），價(jià)格低。而缺點(diǎn)是穩(wěn)壓精度低（±8～10%）工作壽命短，它適用于家庭給空調(diào)器供電。
大功率補(bǔ)償型——凈化型穩(wěn)壓器（含精密型穩(wěn)壓器）
它用補(bǔ)償環(huán)節(jié)實(shí)現(xiàn)輸出電壓的穩(wěn)定，易實(shí)現(xiàn)微機(jī)控制。
