美國GE模塊IC756ADV010K-98美國GE模塊IC756ADV010K-98


擴展資料

工作原理如下:變頻壓縮機運轉的頻率高低，通過由室外機電腦板向功率模塊輸入變頻壓縮機運行控制信號，經功率模塊逆變
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回轉數，功率模塊輸出的電壓、電流和頻率越高。

變頻壓縮機運轉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，變頻壓縮機運轉頻率及輸出功率就會
越低。功率模塊內部是由三組（每組兩只）大功率的開關三極管組成，其作用是將輸入模塊的直流電壓通過三極管的開關作用
逆變為驅動壓縮機的三相交流電源。

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點,以及MOSFET(場效應晶體管)高輸入阻抗、高開關頻
率和低驅動功率的優點。

而且IPM內部集成了邏輯、控制、檢測和保護電路，使用起來方便,不僅減小了系統的體積以及開發時間，也大大增強了系統的
可靠，適應了當今功率器件的發展方向——模塊化、復合化和功率集成電路(PIC)，在電力電子領域得到了越來越廣泛的應用。
