Abstract: The electromagnetic compatibility forward design of a fan used in a space station was carried out from the aspects of suppressing conducted interference and radiation interference. The filter circuit design, component selection, cable protection and structural shielding were discussed in detail, and experimental verification was carried out by using identification products. The results show that the EMC design can effectively suppress the electromagnetic interference of the product and meet the requirements of the space station construction code.
