For user reference, waveforms of the input current and voltage at the nominal input voltage
mains and nominal load conditions are shown in
mains and nominal load conditions are shown in
and
.
The power factor (PF) and the total harmonic distortion (THD) have been measured too and
the results are shown in
the results are shown in
. As visible, the PF remains close to unity throughout
the input voltage mains and the total harmonic distortion is very low.
