摘　　要：介绍了IR2110驱动器的内部结构和特点。对驱动电路中瞬态问题作了具体分析,提出了几种简单有效的抗干扰方法,如直流母线上加继电器,布线路板时考虑栅极驱动电路中的杂散参数,串联限流电阻提升负过冲免疫力等,并在实际应用中验证了它们的有效性。Introduction was made to the structure and characteristic of IR2110. The instantaneous problem on driving circuit is analyzed in detail. There are some simple and available methods of anti-jamming, such as adding relay on DC, designing PCB board in reason to decrease separate parameters, adding series resistance to enhance the immunity of negative over voltage. Their validity has been confirmed in the practical application.
