Ahhh Peebee,
The rectifier is not part of the power conversion. It is there ONLY to replenish the dc source when the inverter is off line. After all, when the ac line power disappears, is it your belief that the "charger rectifier" is involved in the sourcing of AC to the load ?
If so, you must tell us all how this is possible with no input to that function!
In your opinion, a UPS is an AC to AC converter. Seems you and IEEE are in total disagreement.
Also, the laws of physics are in danger of being repealed if you continue to insist that a UPS has an AC to AC involvement.
When the ac line power disappears, does not the input AC disappear.... and then is it not just a relationship between the batteries and the inverter. The inverter inverts the DC from the batteries to AC ?
I sense that will never change your belief, and so, further discussion is of little value and a waste of bandwidth.
I'll stick with the laws of physics and the IEEE.
Oh, FYI, I'm working on a design that uses a fuel cell to provide the DC power for the "INVERTER". No battery, No AC to DC conversion or Battery charger.
Perhaps you'd care to suggest a name for this product since it obviously doesn't conform to your definition of a "UPS" .
