Harmonic content measurement

The board has been tested according to the European standard EN61000-3-2 class-D and

Japanese standard JEITA-MITI Class-D, at both nominal input voltage mains. As reported in

graphs that follow, the circuit is capable of reducing the harmonics well below the limits of

both regulations.

At the bottom of the diagrams, the total harmonic distortion and power factor measurements

are also reported. The values in all conditions provide a clear overview of the correct

functionality of the PFC.
