Outline of Final Research Achievements |
In this study, some active filtering technologies are researched and developed to reduce common-mode noise in both low frequency band of 9 kHz - 150 kHz and more than 30 MHz where a problem would be actualized. The developed noise reduction methods have showed that noise reduction was possible in all frequency bands from the low frequency band, including the switching frequency, to the high frequency band of up to 100 MHz. Particularly, proposed passive common-noise canceller(PCC) can suppress the commo-mode noise up to 50 dB in a frequency band from the switching frequency to around 10 MHz and it has no limitation of the application capacity.
