【摘要】：碳化硅(SiC)混合絕緣柵雙極型晶體管(IGBT)功率器件具有高頻、高效率、高功率、耐高溫、抗輻射等優(yōu)點(diǎn)。以下一代地鐵列車為目標(biāo),對(duì)SiC混合IGBT功率器件與普通IGBT功率器件在通態(tài)損耗、開關(guān)損耗、總損耗等方面進(jìn)行了研究,提出了下一代地鐵列車采用SiC混合IGBT功率器件后的調(diào)制方式,并進(jìn)行了研究。實(shí)驗(yàn)結(jié)果表明,與普通IGBT相比,SiC混合IGBT的功耗約減小30%,開關(guān)頻率的提高也有效降低了輸出諧波,減小了電機(jī)脈動(dòng)轉(zhuǎn)矩,從而使整個(gè)系統(tǒng)的效率得到大幅提高。
[Abstract]:Sic (sic) hybrid insulated gate bipolar transistor (IGBT) power device has the advantages of high frequency, high efficiency, high power, high temperature resistance, radiation resistance and so on. Taking the next generation subway train as the target, the on state loss, switching loss and total loss of SiC hybrid IGBT power device and ordinary IGBT power device are studied. The modulation scheme of the next generation subway train using SiC hybrid IGBT power device is proposed and studied. The experimental results show that compared with conventional IGBT, the power consumption of sic hybrid IGBT is reduced by about 30%, and the increase of switching frequency can effectively reduce the output harmonics and motor torque ripple, thus greatly improving the efficiency of the whole system.
