摘要
Abstract
The issue of excessive radiation caused by electromagnetic interference from switch power supplies in fire control equipment is focused on.Based on the mixed suppression principle of differential mode and common mode,a miniaturized active filtering module is made with electromagnetic interference cancellation technology.The module size is 25.4 mm × 25.4 mm × 6.0 mm,meeting the requirements of low profile and easy for circuit board integration.After the actual measurement,it can suppress power interference in the 10 kHz～10 MHz frequency band and meet the relevant electromagnetic compatibility requirements of GJB 151B.Through actual measurement and comparison,it is found that compared with passive filtering,it has such advantages as small size,low cost,and stable filtering performance,etc.关键词
