| 目前主流的伺服驅(qū)動(dòng)器均采用數(shù)字信號(hào)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(guò)電壓、過(guò)電流、過(guò)熱、欠壓等故障檢測(cè)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)過(guò)程對(duì)驅(qū)動(dòng)器的沖擊。功率驅(qū)動(dòng)單先通過(guò)三相全橋整流電路對(duì)輸入的三相電或者市電進(jìn)行整流，得到相應(yīng)的直流電。經(jīng)過(guò)整流好的三相電或市電，再通過(guò)三相正弦PWM電壓型逆變器變頻來(lái)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)過(guò)程可以簡(jiǎn)單的說(shuō)就是AC-DC-AC的過(guò)程。整流單元（AC-DC）主要的拓?fù)潆娐肥侨嗳珮虿豢卣麟娐贰?/td> |
