One of the main purposes of a PFC pre-conditioner is the correction of input current 
distortion, decreasing the harmonic contents below the limits of the relevant regulations. 
Therefore, this demonstration board has been tested according to the European standard 
EN61000-3-2 class-D and Japanese standard JEITA-MITI Class-D, at full load at both the 
nominal input voltage mains.  

The circuit is able to reduce the harmonics well below the limits of both regulations from full 
load down to light load (measurements are shown in 

 and 

). Please note that all 

measures and waveforms have been done using a Pi-filter for filtering the noise coming from 
the circuit, using a 20 mH common

-

mode choke and two 470NF-X2 filter capacitors.
