49.車規級寬禁帶(dai)半導(dao)體IGBT模塊

【所(suo)屬領(ling)域】核心電子元器件

【中央(yang)企業名(ming)稱(cheng)】東風汽(qi)車集團(tuan)有限公司

【成(cheng)(cheng)果簡介】各類新能(neng)(neng)源汽車(che)(che)逆(ni)變(bian)(bian)器核心(xin)部件是(shi)(shi)功(gong)率半導(dao)體模塊(kuai)，負責將電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)轉化為可調的(de)(de)(de)(de)(de)(de)交流(liu)(liu)輸出到電(dian)(dian)(dian)(dian)(dian)(dian)機。對功(gong)率半導(dao)體模塊(kuai)的(de)(de)(de)(de)(de)(de)耐壓(ya)能(neng)(neng)力、電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)能(neng)(neng)力和耐久壽命(ming)均有很高(gao)要求。IGBT是(shi)(shi)能(neng)(neng)源變(bian)(bian)換與傳輸的(de)(de)(de)(de)(de)(de)核心(xin)器件，其(qi)作(zuo)用是(shi)(shi)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)和直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)(de)轉換，同時IGBT還承(cheng)擔電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)(de)(de)高(gao)低(di)轉換的(de)(de)(de)(de)(de)(de)功(gong)能(neng)(neng)。IGBT是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)的(de)(de)(de)(de)(de)(de)核心(xin)技術之(zhi)一，IGBT的(de)(de)(de)(de)(de)(de)好壞(huai)直接影(ying)響(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)功(gong)率的(de)(de)(de)(de)(de)(de)釋(shi)放速度(du)。目前，IGBT大約占電(dian)(dian)(dian)(dian)(dian)(dian)機控制器總成(cheng)(cheng)本(ben)的(de)(de)(de)(de)(de)(de)40%以上，而電(dian)(dian)(dian)(dian)(dian)(dian)機驅(qu)動(dong)系統(tong)占整(zheng)車(che)(che)成(cheng)(cheng)本(ben)的(de)(de)(de)(de)(de)(de)20%～30%，也就(jiu)是(shi)(shi)說IGBT占整(zheng)車(che)(che)成(cheng)(cheng)本(ben)的(de)(de)(de)(de)(de)(de)7%～10%，是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)里(li)除電(dian)(dian)(dian)(dian)(dian)(dian)池外最昂貴的(de)(de)(de)(de)(de)(de)部件。東風公司(si)開發自主耐壓(ya)能(neng)(neng)力達750V，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)密度(du)250A/cm2,工作(zuo)溫(wen)度(du)175℃以上，低(di)損耗(hao)，可廣泛應用于(yu)新能(neng)(neng)源，電(dian)(dian)(dian)(dian)(dian)(dian)機驅(qu)動(dong)等領域。

【主要指標】

1.耐壓(ya)BV：大于(yu)750V

2.電流密度：大于250A/cm2

3.最大開關(guan)頻率：大于15kHz

4.熱(re)阻：小于(yu)120K/kW

5.秒級功率(lv)循環次(ci)(ci)數：大于45000次(ci)(ci)

【應用推廣需求】

1.應用推(tui)廣方(fang)式：銷售(shou)

2.應用推廣領域(yu)：新能源(yuan)汽車(che)。
