| Abstract: | Based on the analysis of high frequency section EMI power source filter＇s insertion loss, introduced a measure method to decrease grounding resistance and inductance connection. Furthermore,analyzed these two grounding methods and stated that proper grounding method can efficiently enhance filter＇s capability to suppress interference. As a result,measuring results can reflect filter＇s performance better. |
