電子(zi)變壓器(qi)是什么
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)變(bian)(bian)(bian)壓(ya)器又稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)變(bian)(bian)(bian)壓(ya)器，固(gu)態(tai)變(bian)(bian)(bian)壓(ya)器和(he)柔性(xing)變(bian)(bian)(bian)壓(ya)器，是一(yi)(yi)(yi)種(zhong)(zhong)(zhong)通(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)技術(shu)實(shi)現能量傳遞和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)變(bian)(bian)(bian)換(huan)的(de)新型變(bian)(bian)(bian)壓(ya)器。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)變(bian)(bian)(bian)壓(ya)器是一(yi)(yi)(yi)種(zhong)(zhong)(zhong)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)變(bian)(bian)(bian)換(huan)技術(shu)與基于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)感應原理的(de)高頻電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能變(bian)(bian)(bian)換(huan)技術(shu)進行(xing)結合，實(shi)現將一(yi)(yi)(yi)種(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)特征的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能變(bian)(bian)(bian)換(huan)為另一(yi)(yi)(yi)種(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)特征的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能的(de)靜止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)設備。這(zhe)里所說的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)特征主要是指(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(或電流)的(de)幅值、頻率、相位(wei)、相數、相序和波形等方面。
電子變(bian)壓器(qi)工作原理
電(dian)(dian)子變(bian)(bian)壓(ya)(ya)器是(shi)一(yi)種新型的(de)電(dian)(dian)能轉換(huan)設備(bei)(bei)，它(ta)不僅具備(bei)(bei)傳統電(dian)(dian)力(li)變(bian)(bian)壓(ya)(ya)器所具有的(de)電(dian)(dian)壓(ya)(ya)變(bian)(bian)換(huan)、電(dian)(dian)氣隔離和能量(liang)傳遞(di)等基本功(gong)能，還能夠實(shi)現電(dian)(dian)能質量(liang)的(de)調節、系(xi)統潮流(liu)的(de)控(kong)(kong)(kong)制以(yi)(yi)及無功(gong)功(gong)率補償等其它(ta)附加功(gong)能。電(dian)(dian)力(li)電(dian)(dian)子變(bian)(bian)壓(ya)(ya)器之(zhi)所以(yi)(yi)能夠實(shi)現這些附加功(gong)能，主(zhu)要是(shi)因為它(ta)通過引入電(dian)(dian)力(li)電(dian)(dian)子變(bian)(bian)換(huan)技術(shu)及控(kong)(kong)(kong)制技術(shu)之(zhi)后(hou)，能夠對(dui)變(bian)(bian)壓(ya)(ya)器的(de)原(yuan)方和副方的(de)電(dian)(dian)壓(ya)(ya)或(huo)者電(dian)(dian)流(liu)的(de)幅值、相位進行靈(ling)活(huo)的(de)處理和控(kong)(kong)(kong)制，并且可(ke)以(yi)(yi)根(gen)據實(shi)際需要對(dui)系(xi)統的(de)潮流(liu)進行控(kong)(kong)(kong)制。因而電(dian)(dian)力(li)電(dian)(dian)子變(bian)(bian)壓(ya)(ya)器可(ke)以(yi)(yi)實(shi)現更為穩定和靈(ling)活(huo)的(de)輸電(dian)(dian)，可(ke)以(yi)(yi)解(jie)決當今電(dian)(dian)力(li)系(xi)統中所存在(zai)的(de)許多問題，其應用的(de)前(qian)景(jing)也將十分(fen)廣闊。
電子變壓器(qi)(qi)在傳(chuan)統照明燈具(ju)中的(de)應用十分普遍(bian)，如日光燈、廣告燈等等幾乎(hu)都(dou)可以使用電子變壓器(qi)(qi)，并且采用電子變壓器(qi)(qi)之(zhi)后，可以省掉啟動(dong)器(qi)(qi)。在LED照(zhao)明中，新品也大都采用電子(zi)變壓(ya)器。主要是(shi)(shi)電子(zi)變壓(ya)器在(zai)變壓(ya)功能上，效率高、成本底，節約鐵(tie)銅材料，結(jie)構小，重量輕。不足(zu)的是(shi)(shi)耐壓(ya)和耐大電流沖(chong)擊性能較鐵(tie)質變壓(ya)器差。
