I have two chinese 32V 5A switching mode power supplies for my chinese TPA3251/TPA3255 amplifiers.
As far as I know, one can use low-pass filter or take the following noise measures for switching mode power supply in order to reduce electromagnetic interference.
Do most switching mode power supplies take noise measures?
According to TriField EM100, my chinese switching mode power supplies seem to reduce differential mode noise a little bit, but I don't know whether it reduces common mode noise because TriField EM100 doesn't measure common mode noise. To measure common mode noise, I may need a proper oscilloscope.
