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.
