Test results and significant waveforms

For user reference, waveforms of the input current and output voltage at 230 Vac and 100

Vac input voltage mains during nominal and 70 W load operation, are reported in Figure 7

and 8.

As shown in the images, the current shape is very good, and sinewave has very low

distortion as confirmed by the low THD in all line and load conditions.
