目前主流的伺服驅(qū)動(dòng)器均采用數(shù)字處理器（DSP）作為控制核心， 可以實(shí)現(xiàn)比較復(fù)雜的控制算法，實(shí)現(xiàn)數(shù)字化、網(wǎng)絡(luò)化和智能化。功率器件普遍采用以智能功率模塊（IPM）為核心設(shè)計(jì)的驅(qū)動(dòng)電路,IPM內(nèi)部集成了驅(qū)動(dòng)電路,同時(shí)具有過電壓、過電流、過熱、欠壓等故障檢測保護(hù)電路,在主回路中還加入軟啟動(dòng)電路,以減小啟動(dòng)對驅(qū)動(dòng)器的沖擊。功率驅(qū)動(dòng)單元首先通過三相全橋整流電路對輸入的三相電或者市電進(jìn)行整流，相應(yīng)的直流電。經(jīng)過整流好的三相電或市電，再通過三相正弦PWM電壓型逆變器變頻來驅(qū)動(dòng)三相永磁式同步交流伺服電機(jī)。功率驅(qū)動(dòng)單元的整個(gè)可以簡單的說是AC-DC-AC的。整流單元（AC-DC）主要的拓?fù)潆娐肥侨嗳珮?a b="https://baike.baidu.com/item/%E4%B8%8D%E6%8E%A7%E6%95%B4%E6%B5%81%E7%94%B5%E8%B7%AF" target="b">不控整流電路。
