矿用变频器功率器件选型及其驱动保护设计

Type Selection and Design of Drive and Protection of Power Device of Mine-used Frequency Converter

分析了煤矿井下设备对变频器功率器件IGBT的需求和在IGBT选型时需要考虑的电气参数,介绍了基于2SD315模块的IGBT驱动保护电路的设计。实际应用表明,采用文中介绍的方法选用的IGBT和设计的驱动保护电路后,变频器运行稳定,IGBT驱动有效,保护完善。

The paper analyzed requiements of underground devices for power device IGBT of frequency converter and electrical parameters which should be considered in type selection of IGBT,and designed a drive and protection circuit of IGBT by use of 2SD315 module.The actual application showed that frequency converter is stable in running and effective in IGBT drive with perfect protection after using selected IGBT and designed drive and protection circuit by use of methods described in the paper.
