二極(ji)管功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)是(shi)一種電(dian)(dian)(dian)子器(qi)件(jian)(jian)(jian)，具有(you)高(gao)效(xiao)能(neng)和(he)高(gao)可(ke)靠性的(de)(de)特(te)點，適用于各種電(dian)(dian)(dian)路應用。它是(shi)一種半導(dao)(dao)(dao)體器(qi)件(jian)(jian)(jian)，由P型和(he)N型半導(dao)(dao)(dao)體材料組成。在(zai)正(zheng)向偏置(zhi)時，二極(ji)管能(neng)夠將電(dian)(dian)(dian)流從P區域傳(chuan)導(dao)(dao)(dao)到(dao)N區域，形成導(dao)(dao)(dao)通狀態(tai)(tai)；而在(zai)反(fan)向偏置(zhi)時，二極(ji)管則(ze)能(neng)夠阻(zu)止電(dian)(dian)(dian)流的(de)(de)流動，形成截(jie)止狀態(tai)(tai)。二極(ji)管功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)的(de)(de)高(gao)效(xiao)能(neng)主要體現在(zai)其低(di)電(dian)(dian)(dian)壓降和(he)高(gao)電(dian)(dian)(dian)流承受能(neng)力(li)上。由于二極(ji)管的(de)(de)導(dao)(dao)(dao)通特(te)性，其正(zheng)向電(dian)(dian)(dian)壓降非常(chang)(chang)(chang)低(di)，通常(chang)(chang)(chang)只有(you)幾百(bai)毫伏，這使得二極(ji)管功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)在(zai)電(dian)(dian)(dian)路中(zhong)(zhong)能(neng)夠起到(dao)快速(su)開(kai)關的(de)(de)作(zuo)用，從而實現高(gao)效(xiao)能(neng)的(de)(de)能(neng)量(liang)轉換(huan)。此外(wai)，二極(ji)管功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)還能(neng)夠承受較大的(de)(de)電(dian)(dian)(dian)流，通常(chang)(chang)(chang)可(ke)達(da)幾十安培，這使得它能(neng)夠在(zai)高(gao)功率(lv)(lv)(lv)電(dian)(dian)(dian)路中(zhong)(zhong)穩(wen)定(ding)工作(zuo)，不(bu)易受到(dao)過載(zai)或短(duan)路等因素(su)的(de)(de)影響。CypressIGBT功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)銷售價(jia)格三極(ji)管功率(lv)(lv)(lv)器(qi)件(jian)(jian)(jian)的(de)(de)價(jia)格相對較低(di)，成本較為可(ke)控，適合大規模生產和(he)應用。

IGBT功率(lv)器件由(you)P型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)和(he)(he)N型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)組(zu)成，中(zhong)間有一(yi)層PN結(jie)(jie)。在正(zheng)常工(gong)(gong)作(zuo)(zuo)(zuo)狀態(tai)下，N型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)中(zhong)的(de)(de)(de)(de)少量載(zai)(zai)流(liu)子會(hui)向(xiang)(xiang)P型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)擴散，形成空穴；而在反向(xiang)(xiang)電(dian)(dian)壓(ya)(ya)作(zuo)(zuo)(zuo)用(yong)下，P型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)中(zhong)的(de)(de)(de)(de)多數載(zai)(zai)流(liu)子會(hui)向(xiang)(xiang)N型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)擴散，形成電(dian)(dian)子。這種載(zai)(zai)流(liu)子的(de)(de)(de)(de)擴散和(he)(he)復合過程使得(de)PN結(jie)(jie)兩(liang)(liang)側(ce)的(de)(de)(de)(de)電(dian)(dian)場(chang)發(fa)生(sheng)變(bian)化，從而產生(sheng)一(yi)個與輸入電(dian)(dian)壓(ya)(ya)和(he)(he)電(dian)(dian)流(liu)方向(xiang)(xiang)相反的(de)(de)(de)(de)電(dian)(dian)壓(ya)(ya)。這個電(dian)(dian)壓(ya)(ya)就是(shi)IGBT的(de)(de)(de)(de)開關損耗。為(wei)了減(jian)小(xiao)開關損耗，提高器件的(de)(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)效率(lv)，通(tong)(tong)常采用(yong)柵(zha)極電(dian)(dian)壓(ya)(ya)來控(kong)制PN結(jie)(jie)兩(liang)(liang)側(ce)的(de)(de)(de)(de)電(dian)(dian)場(chang)。具(ju)體(ti)來說，當(dang)柵(zha)極電(dian)(dian)壓(ya)(ya)為(wei)負(fu)時，N型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)中(zhong)的(de)(de)(de)(de)載(zai)(zai)流(liu)子向(xiang)(xiang)P型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)擴散，使得(de)PN結(jie)(jie)兩(liang)(liang)側(ce)的(de)(de)(de)(de)電(dian)(dian)場(chang)減(jian)弱(ruo)；而當(dang)柵(zha)極電(dian)(dian)壓(ya)(ya)為(wei)正(zheng)時，P型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)中(zhong)的(de)(de)(de)(de)載(zai)(zai)流(liu)子向(xiang)(xiang)N型(xing)(xing)(xing)半(ban)(ban)導(dao)(dao)體(ti)擴散，使得(de)PN結(jie)(jie)兩(liang)(liang)側(ce)的(de)(de)(de)(de)電(dian)(dian)場(chang)增強。這樣，通(tong)(tong)過改變(bian)柵(zha)極電(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)大小(xiao)和(he)(he)方向(xiang)(xiang)，可(ke)以實現對IGBT導(dao)(dao)通(tong)(tong)狀態(tai)的(de)(de)(de)(de)控(kong)制。
