mains cycles it comes back to the nominal value. The situation is different if we check the
performance of a controller without the V
using the L6562A delivering similar output power. In case of a mains dip from 140 Vac to 90
Vac, the output voltage variation is not very different, but the output voltage requires a longer
time to restore the original value.
Testing with a wider voltage variation (e.g. 265 Vac to 90 Vac), the output voltage variation of
a PFC without the voltage feed-forward fast discharge is emphasized even more.
