characteristics  of  the  power  supply  common  mode  and  differential  mode  interference,  the 

interference  can  be  classified  into  3  ranges  by  its  distribution:  150kHz~500kHz  is  mainly 

for  differential  mode  interference;  500kHz~5MHz  is  for  differential  mode  and  common 

mode interference; 5MHz~30 MHz is mainly for common mode interference.
