低壓通用變頻輸(shu)出電(dian)壓為(wei)380～650V，輸(shu)出功率為(wei)0.75～400kW，工(gong)作頻率為(wei)0～400Hz，它的(de)主(zhu)電(dian)路都采用交—直—交電(dian)路。其控(kong)制方(fang)式經歷了以(yi)下四代：

正弦脈(mo)寬調制(zhi)(zhi)(SPWM)控(kong)(kong)制(zhi)(zhi)方(fang)式(shi)→電壓空間矢量(SVPWM)控(kong)(kong)制(zhi)(zhi)方(fang)式(shi)→矢量控(kong)(kong)制(zhi)(zhi)(VC)方(fang)式(shi)→直接轉(zhuan)矩(ju)控(kong)(kong)制(zhi)(zhi)(DTC)方(fang)式(shi)→矩(ju)陣式(shi)交—交控(kong)(kong)制(zhi)(zhi)方(fang)式(shi)

矩陣式交(jiao)—交(jiao)控(kong)制方式的具體(ti)方法：

1、控制定子磁鏈(lian)引入定子磁鏈(lian)觀測(ce)器(qi)，實(shi)現(xian)無速(su)度傳感器(qi)方式；

2、自動識別(ID)依靠電機數(shu)學(xue)模型，對電機參(can)數(shu)自動識別；

3、西門子變頻器6RA70啟動報警F004維修方法算(suan)出實際(ji)值對應(ying)定子阻抗、互(hu)感、磁飽(bao)和(he)因素、慣(guan)量等算(suan)出實際(ji)的轉(zhuan)矩、定子磁鏈、轉(zhuan)子速度進行實時控(kong)制；

4、實現Band—Band控(kong)(kong)制(zhi)按磁鏈(lian)和轉矩的Band—Band控(kong)(kong)制(zhi)產生PWM信號(hao)，對逆變器開(kai)關狀(zhuang)態進(jin)行(xing)控(kong)(kong)制(zhi)。

矩(ju)陣式(shi)交—交變(bian)頻具有快速(su)的轉(zhuan)矩(ju)響應(<2ms)，很(hen)高的速(su)度(du)精(jing)度(du)(±2%，無PG反饋)，高轉(zhuan)矩(ju)精(jing)度(du)(<+3%)；同(tong)時還具有較高的起動轉(zhuan)矩(ju)及高轉(zhuan)矩(ju)精(jing)度(du)，尤其(qi)在低速(su)時(包括(kuo)0速(su)度(du)時)，可輸出150%～200%轉(zhuan)矩(ju)。
