本文针对航空航天某型泵用动力系统在器上出现母线电流异常跳变现象进行了分析,对控制器中驱动模块限流保护电路异常动作的机理进行分析及试验验证,确定了异常母线跳变的问题原因,并采取了措施.该驱动系统电磁兼容性问题的解决,提高了器件及产品的可靠性,并为同类问题解决提供了思路.
Analysis and Thinking of the Bus Current Jump Caused by the EMC Problem in the Electric Drive System of Pump
This article analyzed the fault of abnormal shutdown of a certain type of motor during acceptance testing,analyzed and verified the mechanism of power MOSFET short circuit failure in the driver,identified the cause of the abnormal shutdown problem,and took improvement measures.In response to changes in the parameters of imported components,it provided a reference path for solving similar problems.
