Rectification Analysis and Verification on Electromagnetic Compatibility of Torpedo Support Equipment

The index of torpedo support equipment exceeds the standard in electromagnetic compatibility(EMC) test. In view of this problem, the composition and electromagnetic characteristics of the equipment were analyzed, and the weak links in the EMC design of the equipment were determined. Targeted rectification measures such as chassis shielding treatment, power filter introduction, and internal and external cable treatment were taken. The comparison test shows that the conducted emission and radiation emission indexes of the equipment are significantly reduced after rectification, which meets the limit lines of the national military standard. It proves that the rectification measures are effective and can provide a reference for the EMC rectification of other equipment.
