<div>　　高输入阻抗，低驱动功率： IGBT的栅极采用MOS结构，输入阻抗高，驱动功率小，简化了驱动电路设计。 </div> <div> <br> </div> <div>　　低导通压降，高电流密度： IGBT继承了BJT 的低导通压降特性，能够承受较高的电流密度，降低导通损耗。 </div> <div> <br> </div> <div>　　高开关频率，低开关损耗： IGBT的开关速度比 BJT 快，开关损耗低，适用于高频应用场合。 </div> <div> <br> </div> <div>　　?？榛杓?，易于安装维护：igbt模块将多个芯片和电路集成在一起，结构紧凑，便于安装和维护。 </div> <div> <br> </div> </div> <div id="qroc9ovti" class="datumrelate"> <span>下一篇：</span> <a
