531X309SPCAJG1531X309SPCAJG1 各牽引機(jī)車車輛制造商為滿足對(duì)變頻器工作特性所提出的要求,進(jìn)行結(jié)構(gòu)設(shè)計(jì)。設(shè)計(jì)時(shí)考慮到了與冷卻系統(tǒng)配套的外形尺寸不能超標(biāo),并且要保證zui大限度地符合在機(jī)車車輛上的布置條件。對(duì)這些結(jié)構(gòu)設(shè)計(jì)進(jìn)行比較后,發(fā)現(xiàn)相互間的差別很大。IGBT晶體管的換向特性和正向安伏特性有待進(jìn)一步改進(jìn)。但是近10年來(lái),在功率半導(dǎo)體技術(shù)方面未見(jiàn)有任何突破。(美國(guó))現(xiàn)貨 *正品 11-11*供應(yīng)中心
