49.車規(gui)級寬禁帶半(ban)導體(ti)IGBT模塊

【所屬(shu)領域】核(he)心(xin)電子元器件

【中央企業(ye)名稱(cheng)】東(dong)風汽車集團有限公司

【成(cheng)果簡介】各(ge)類新(xin)能(neng)源汽車(che)(che)逆變器核(he)(he)心(xin)(xin)部(bu)(bu)件是(shi)(shi)功率半(ban)導體模塊(kuai)，負(fu)責(ze)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)轉(zhuan)(zhuan)化為(wei)可調(diao)的(de)(de)(de)交(jiao)(jiao)流輸出到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機。對功率半(ban)導體模塊(kuai)的(de)(de)(de)耐壓能(neng)力、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流能(neng)力和耐久壽命均(jun)有(you)很高要求(qiu)。IGBT是(shi)(shi)能(neng)源變換與傳(chuan)輸的(de)(de)(de)核(he)(he)心(xin)(xin)器件，其作(zuo)用是(shi)(shi)交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)轉(zhuan)(zhuan)換，同時IGBT還承擔電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)(de)高低轉(zhuan)(zhuan)換的(de)(de)(de)功能(neng)。IGBT是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)的(de)(de)(de)核(he)(he)心(xin)(xin)技術之一，IGBT的(de)(de)(de)好壞直接影響電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)功率的(de)(de)(de)釋放速度。目前(qian)，IGBT大約占電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機控(kong)制器總成(cheng)本的(de)(de)(de)40%以上(shang)，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機驅動(dong)(dong)(dong)系統占整車(che)(che)成(cheng)本的(de)(de)(de)20%～30%，也就是(shi)(shi)說IGBT占整車(che)(che)成(cheng)本的(de)(de)(de)7%～10%，是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)里除(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池外最(zui)昂貴的(de)(de)(de)部(bu)(bu)件。東風公(gong)司(si)開(kai)發(fa)自主耐壓能(neng)力達750V，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流密度250A/cm2,工(gong)作(zuo)溫(wen)度175℃以上(shang)，低損耗，可廣泛應用于(yu)新(xin)能(neng)源，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機驅動(dong)(dong)(dong)等(deng)領域。

【主要指標】

1.耐壓(ya)BV：大于750V

2.電流密度：大于250A/cm2

3.最(zui)大開關頻率：大于15kHz

4.熱(re)阻(zu)：小(xiao)于(yu)120K/kW

5.秒(miao)級功(gong)率(lv)循環次數：大于45000次

【應用推廣需求】

1.應用推廣方式(shi)：銷售

2.應(ying)用推廣(guang)領域(yu)：新能源汽(qi)車(che)。
