美國GE模塊IC756CDV010E-98
工作原理如下:變頻壓縮機(jī)運(yùn)轉(zhuǎn)的頻率高低，通過由室外機(jī)電腦板向功率模塊輸入變頻壓縮機(jī)運(yùn)行控制信號，經(jīng)功率模塊逆變
所輸出的交流電壓、交流電流和交流頻率的高低來控制壓縮機(jī)回轉(zhuǎn)數(shù)，功率模塊輸出的電壓、電流和頻率越高。
變頻壓縮機(jī)運(yùn)轉(zhuǎn)頻率及輸出功率就越高，反之，功率模塊輸出的電壓、電流和頻率越低，變頻壓縮機(jī)運(yùn)轉(zhuǎn)頻率及輸出功率就會
越低。功率模塊內(nèi)部是由三組（每組兩只）大功率的開關(guān)三極管組成，其作用是將輸入模塊的直流電壓通過三極管的開關(guān)作用
逆變?yōu)轵?qū)動壓縮機(jī)的三相交流電源。
功率模塊輸入的直流電壓P+與N-之間電壓通常為310V左右，而功率模塊U、V、W三端其中任意兩相之間輸出的交流電壓一般在
50V-200V。注：U+、V+、W+為上臂，U-、V-、W-為下臂。
功率模塊是功率電力電子器件按一定的功能組合再灌封成一個模塊。
作用：具有GTR(大功率晶體管)高電流密度、低飽和電壓和耐高壓的優(yōu)點(diǎn),以及MOSFET(場效應(yīng)晶體管)高輸入阻抗、高開關(guān)頻
率和低驅(qū)動功率的優(yōu)點(diǎn)。
而且IPM內(nèi)部集成了邏輯、控制、檢測和保護(hù)電路，使用起來方便,不僅減小了系統(tǒng)的體積以及開發(fā)時間，也大大增強(qiáng)了系統(tǒng)的
可靠，適應(yīng)了當(dāng)今功率器件的發(fā)展方向——模塊化、復(fù)合化和功率集成電路(PIC)，在電力電子領(lǐng)域得到了越來越廣泛的應(yīng)用。
