Harmonic content at nominal mains voltage
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 Japanese JEIDA-MITI Class-C standard and
European EN61000-3-2 Class-C standard, at a full load and both nominal input voltage
mains.
Figure 46. Measurement at 100 VAC, 50 Hz, PIN = 10.95 W, POUT = 9.5 W, PF = 0.9880
Figure 47. Measurement at 230 V, 50 Hz, PIN = 10.88 W, POUT = 9.48 W, PF = 0.9220
Figure 46 and Figure 47 show as the harmonics respect the limits for the Class-C
equipment.
