扩展资料

工作原理如下:变频压缩机运转的频率高低，通过由室外机电脑板向功率模块输入变频压缩机运行控制信号，经功率模块逆变

所输出的交流电压、交流电流和交流频率的高低来控制压缩机回转数，功率模块输出的电压、电流和频率越高。

变频压缩机运转频率及输出功率就越高，反之，功率模块输出的电压、电流和频率越低，变频压缩机运转频率及输出功率就会

越低。功率模块内部是由三组（每组两只）大功率的开关三极管组成，其作用是将输入模块的直流电压通过三极管的开关作用

逆变为驱动压缩机的三相交流电源。

功率模块输入的直流电压P+与N-之间电压通常为310V左右，而功率模块U、V、W三端其中任意两相之间输出的交流电压一般在

50V-200V。注：U+、V+、W+为上臂，U-、V-、W-为下臂。

功率模块是功率电力电子器件按一定的功能组合再灌封成一个模块。

作用：具有GTR(大功率晶体管)高电流密度、低饱和电压和耐高压的优点,以及MOSFET(场效应晶体管)高输入阻抗、高开关频

率和低驱动功率的优点。

而且IPM内部集成了逻辑、控制、检测和保护电路，使用起来方便,不仅减小了系统的体积以及开发时间，也大大增强了系统的

可靠，适应了当今功率器件的发展方向——模块化、复合化和功率集成电路(PIC)，在电力电子领域得到了越来越广泛的应用。
