What part of the world are you from?? In some parts of the world, the
first thing people might think when they hear "PFC" would be "Private
First Class"!!

Only if they're military.

No, in a Switched Mode Power Supply, as the load varies, it is
*Switched
On* for more of less of the Alternating Cycle. If the supply's output
(Current/Voltage) is falling below the required (Current/Voltage), the
Switching element/transistor is switched on for more of the input
cycle,
not the input voltage!!

I see. So this is seperate from the yellow one connected across the
mains input?

Yes, the "yellow one connected across the mains input" is a bridge
rectifier, which converts the AC Sinewave input into single polarity
pulses at twice the mains supply frequency.

No it isn't, I mean these ones:

Wacko!!

It hasn't got food in it.

So what's it doing "On", apart from wasting energy??

Keeping water cool.

How much water, and for what purpose??

Three quarters of a tonne. I like cold baths.
