變(bian)(bian)頻器的(de)主電(dian)(dian)(dian)路(lu)大體上(shang)可分為(wei)(wei)兩(liang)類:電(dian)(dian)(dian)壓型是將電(dian)(dian)(dian)壓源的(de)直(zhi)流(liu)(liu)變(bian)(bian)換為(wei)(wei)交(jiao)流(liu)(liu)的(de)變(bian)(bian)頻器，直(zhi)流(liu)(liu)回路(lu)的(de)濾波(bo)是電(dian)(dian)(dian)容;電(dian)(dian)(dian)流(liu)(liu)型是將電(dian)(dian)(dian)流(liu)(liu)源的(de)直(zhi)流(liu)(liu)變(bian)(bian)換為(wei)(wei)交(jiao)流(liu)(liu)的(de)變(bian)(bian)頻器，其直(zhi)流(liu)(liu)回路(lu)濾波(bo)石(shi)電(dian)(dian)(dian)感。

　　非同步電動機的轉矩是電機的(de)磁通(tong)與轉(zhuan)子內流過電(dian)(dian)(dian)(dian)流之(zhi)間相互作用而產(chan)生的(de)，在額定(ding)頻率(lv)下(xia)，如(ru)果電(dian)(dian)(dian)(dian)壓一(yi)定(ding)而只降低(di)頻率(lv)，那麼磁通(tong)就過大，磁回路飽和，嚴重(zhong)時(shi)將燒毀(hui)電(dian)(dian)(dian)(dian)機。因此，頻率(lv)與電(dian)(dian)(dian)(dian)壓要成比例地改變(bian)，即改變(bian)頻率(lv)的(de)同時(shi)控制(zhi)變(bian)頻器輸出電(dian)(dian)(dian)(dian)壓，使電(dian)(dian)(dian)(dian)動機的(de)磁通(tong)保持一(yi)定(ding)，避免弱磁和磁飽和現(xian)象的(de)產(chan)生。這種控制(zhi)方(fang)式(shi)多用於風機、泵類節能型變(bian)頻器。

　　頻率(lv)下降(低速)時(shi),如果輸出(chu)相(xiang)同的功率(lv),則電(dian)流(liu)增加,但(dan)在轉(zhuan)矩一定的條件下,電(dian)流(liu)幾乎不(bu)變。
