【摘要】：碳化硅(SiC)混合绝缘栅双极型晶体管(IGBT)功率器件具有高频、高效率、高功率、耐高温、抗辐射等优点。以下一代地铁列车为目标,对SiC混合IGBT功率器件与普通IGBT功率器件在通态损耗、开关损耗、总损耗等方面进行了研究,提出了下一代地铁列车采用SiC混合IGBT功率器件后的调制方式,并进行了研究。实验结果表明,与普通IGBT相比,SiC混合IGBT的功耗约减小30%,开关频率的提高也有效降低了输出谐波,减小了电机脉动转矩,从而使整个系统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.
