Harmonic content measurement
One of the main purposes of this converter is the correction of input current distortion,
decreasing the harmonic contents below the limits of the actual regulation. Therefore, the
board has been tested according to the European standard EN61000-3-2 Class-C and
Japanese standard JEIDA-MITI Class-C, at full load and both nominal input voltage mains.

board has been tested according to the European standard EN61000-3-2 Class-C and
Japanese standard JEIDA-MITI Class-C, at full load and both nominal input voltage mains.
As shown in figures that follow, the circuit is capable of reducing the harmonics well below
the limits of both regulations.
the limits of both regulations.
The power factor (PF) has been measured also and the results are reported in
shown, the PF remains very close to unity throughout the input voltage mains range.
The waveforms of the input current and voltage at the nominal input voltage mains and full
load condition are illustrated in
