Fig. 3 (My setting of the Fourier Analysis tool):
We can see that in Plot 1, the THD value is so high(=80936.9%). Its looks like not right... Does the PLECS calculate THD value with the DC component(=217.319)?
However, Does the THD value(=5.21%) in Plot 3 calculated with the DC component(=108.66)?
Attached are file of Fig. 1, 2, 3.
