變頻器諧波諧波產(chǎn)生的原因從結(jié)構(gòu)上看，變頻器可分為直接變頻和間接變頻兩大類(lèi)。間接變頻將工頻電流通過(guò)整流器變成直流，然后再經(jīng)過(guò)逆變器將直流換成可控頻率的交流。直接變頻器則將工頻交流變換成可控頻率的交流，沒(méi)有中間環(huán)節(jié)。它的每相都是一個(gè)兩相晶閘管整流裝置反并聯(lián)的可逆線路。正反兩組按一定周期相互切換，在負(fù)荷上就獲得了交變輸出電壓，其幅值決定于各整流裝置的控制角，頻率決定于兩相整流裝置的切換頻率。目前應(yīng)用較多的還是間接變頻器。間接變頻器有三種不同的結(jié)構(gòu)形式：(1)用可控整流器變壓，用逆變器變頻，調(diào)壓調(diào)頻分別是在兩個(gè)環(huán)節(jié)上進(jìn)行，兩者要在控制電路上協(xié)調(diào)配合。(2)用不控整流器整流斬波器變壓|廈門(mén)變頻器維修、逆變器變頻，這種變頻器整流環(huán)節(jié)用斬波器，用脈寬調(diào)壓。(3)用不控整流器整流，PWM(Pulse Width Modulation，脈沖寬度調(diào)制)逆變器同時(shí)變頻，這種變頻器只有采用可控關(guān)斷的全控式器件(加絕緣柵雙極晶休管IGBT等)輸出波形才會(huì)非常逼真的正弦波。 </p> <p> <br /> </p> <p> <br /> </p><p> 變頻器是將工頻電源轉(zhuǎn)換成任意頻率、任意電壓交流電源的一種電氣設(shè)備，變頻器的使用主要是調(diào)整電機(jī)的功率、實(shí)現(xiàn)電機(jī)的變速運(yùn)行。變頻器的組成主要包括控制電路和主電路兩個(gè)部分，其中主電路還包括整流器和逆變器等部件。變頻器的工作原理是通過(guò)控制電路來(lái)控制主電路，主電路中的整流器將交流電轉(zhuǎn)變?yōu)橹绷麟?，直流中間電路將直流電進(jìn)行平滑濾波，逆變器之后將直流電再轉(zhuǎn)換為所需頻率和電壓的交流電，部分變頻器還會(huì)在電路內(nèi)加入CPU等部件，來(lái)進(jìn)行必要的轉(zhuǎn)矩運(yùn)算。廈門(mén)友億佳自動(dòng)化設(shè)備有限公司是一家專(zhuān)業(yè)維修變頻器的公司，維修品牌例如下：三菱變頻器維修，安川變頻器維修，松下變頻器維修，西門(mén)子變頻器維修，ABB變頻器維修，施耐德變頻器維修，倫茨變頻器維修，三墾變頻器維修，日基變頻器維修，明電舍變頻器維修，優(yōu)利康變頻器維修，LG變頻器維修，偉墾變頻器維修，普傳變頻器維修，森蘭變頻器維修，阿爾法變頻器維修，臺(tái)安變頻器維修，愛(ài)得利變頻器維修，海利普變頻器維修，蒙德變頻器維修，匯川變頻器維修，英威騰變頻器維修，易驅(qū)變頻器維修，三晶變頻器維修，中達(dá)變頻器維修，力士樂(lè)變頻器維修等等各品牌。
