Abstract

Recently, LED is being used as various applications such as home lightings, work lightings and so on. EMI noise generated from LED driver have become a problem according to increase the use of LED. In this paper, Active EMI filter composed active and passive components is discribed as a method of solving a problem of EMI. The proposed filter is applied to the 160W LED load to verify performance experimentally. To compare the performance, We did an experiment using the proposed filter and the passive filter on the same 160W LED load and Driver System. As a result, The proposed Active EMI filter attenuated Conduction EMI noise better than any existing passive filter.
