100% on the +200 V output. This figure also highlights the induced effect of this load change
on the PFC pre-regulator output voltage (+400 V on Ch1 track). Both the transitions (from
20% to 100% and from 100% to 20%) are clean and do not show any problem for the output
voltage regulation.
This shows that the proposed architecture is also highly suitable for power supplies
operating with strong load variation without any problems related to the load regulation.
