4 Test results and significant waveforms
4.1 Harmonic content measurement
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 (measurements are shown in Figure 3 and 4) to light load. 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.
