Please do not confuse Power Factor Correction (PFC) with power supply

** OK so far.


Gee, thanks. [Red flag warning!!!]

PFC can be either active or passive,

Careful, a hint of ignorance is showing.

but usually alters the highly capacitive input of SMPSs.

They are not capacitive, there is no phase angle.

Maybe, but you are still a total loon (!!!)



Since the cap(s) draw their maximum
current when at lowest charge (zero cross-over point),

When one uses this many apostrophies, it is customary to ask
Vanna for a vowel and pay for each. You have not done so,
and so it is detracting from your attempted point.




The caps can only draw charging current when the AC supply voltage is
greater than the voltage already on the cap - so ( aside from the very
first cycle ) they charge at AC voltage peaks ONLY !!!!!!!!


Ok !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!



Time for you to go play with the demented Orang-utans


Wait, are you saying we now have a petting zoo?

cool!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!

Which cage are you in, I will stop by and throw you a
peanut. And some lithium.
