摘要
绝缘栅双极型晶体管(IGBT)是电磁搅拌器专用变频电源的、核心功率器件之一,IGBT的可靠运行时刻关系着整个电磁搅拌系统的命脉。此处以电磁搅拌器专用变频电源中IGBT损坏为例,分析了IGBT损坏的常见形式以及原因,并根据原因提出各种不同改进措施,分析各种解决办法利弊后选取最优的方案。实践证明,采取所提出最优的措施后,电磁搅拌器专用变频电源中IGBT损坏的概率大大降低。
Insulated gate bipolar translator(IGBT) is one of the core power components of the special variable frequency power supply for electromagnetic agitator.The reliable operation of IGBT is the lifeblood of the whole electromagnetic agitator system.IGBT damage in the special frequency conversion power supply of electromagnetic agitator as an example is taken,the common forms and causes of IGBT damage are analyzed,various improvement measures are put forward according to the causes,the advantages and disadvantages of various solutions are analyzed,and the best scheme is selected.It is proved that the IGBT damage frequency in the special inverter power supply of electromagnetic agitator is greatly reduced after the optimal measures proposed are adopted.
