Harmonic content measurement

The board has been tested according to the European rule EN61000-3-2 Class-D and

Japanese rule JEIDA-MITI Class-D, at both the nominal input voltage mains. As shown in

Figure 4 and 5 the circuit is able to reduce the harmonics well below the limits of both

regulations.

On the bottom of the diagrams the total harmonic distortion and power factor have been

measured too. The values in all conditions give a clear idea of the correct function of the

PFC even if it has implemented the tracking boost option.
