摘要
绝缘栅双极型晶体管(IGBT)在大功率应用中的电热应力高、磁场环境恶劣,中、高压变频器因IGBT失效而导致的故障率和损毁率都不容忽视,为满足大功率IGBT对灵活可靠的驱动电路的需求,本文基于TLP5214设计了1700 V/600 A IGBT的驱动保护电路,计算了相关的驱动保护电路参数,并进行相应器件的选型。最后,搭建了双脉冲和短路实验平台,对所设计的驱动器进行了实验验证,结果表明,驱动器可以正常开关IGBT,在短路情况下可以检测短路故障并关断IGBT,有较好的应用和推广价值。
Insulated gate bipolar transistor(IGBT)has high electrothermal stress and harsh magnetic field environment in high-power applications.Due to the failure of IGBT,the failure rate and damage rate of medium and high voltage inverter can not be ignored.In order to meet the demand for flexible and reliable driving circuits for high-power IGBTs,this paper designs a driving protection circuit for 1700 V/600 A IGBTs based on the TLP5214,the relevant drive pro⁃tection circuit parameters are calculated,and the selection of the corresponding devices is carried out.Finally,a doublepulse and short-circuit test platform is built to experimentally verify the designed driver,and the results show that the driver can switch the IGBT normally,and can detect short-circuit faults and shut down the IGBT under short-circuit con⁃ditions.It has good application and popularization value.
