Abstract
This application relates to an independent active electromagnetic interference filter module. In one aspect, the filter module includes a first element group including a noise sensing unit provided to sense electromagnetic noise, and a second element group including a compensating unit provided to generate a compensation signal for the electromagnetic noise. The first group and the second group may be respectively mounted on different substrates. According to some embodiments, the filter module can reduce a volume of each element constituting an electromagnetic interference filter module, implement a single modularization of a compact structure. The filter module can also improve electromagnetic interference noise reduction performance and a manufacturing method thereof.
