I am making mini ups circuit as a project and in the project there is a part with variable resistor of 10k and transistor BC548. what I don't understand is that in the description it says that variable resistor and transistor acts as voltage comparator. i really don't know what that means. plz help me out!!

In my opinion use a single ups . If you use 8 ups it lost lot of current as losses .and a lot of places.
Calculate the full Load with the help of an electrical experts and take decision.

The "N" part is significantly slower and has higher capacitance than the "NF" part. That difference may or may not cause trouble in your ups circuit.
Did you replace the MOSFET because it was damaged? Maybe the circuit has another malfunction that killed the MOSFET.

You have to describe your situation and application in detail. Is it the DC pulse or impulse. Level of the DC? pulse width?
The basics would be to turn on a npn transistor and use this transistor to turn on POWER MOSFETS, if you need more power add multiple mosfetets in parallel.
you can see a simple ups circuit to see the mosfet configuratio

Yeah; I certainly agree with your point there.

This circuit works as a comparator. Consider the branch with Vinp. If Vinp increases, then the current through the PMOS differential pair at that end decreases. Hence, the Vds drop on its active NMOS load decreases. For a moment consider that load to be a resistor because of the rds being modeled as a resistor. When the current is decreasing, then,

ups is not constructed in a way to handle long time load . Transformators are not choosen to work in continuos mode operation. Then switching MOsFET's hs to be put onto radiators. better will be increase number of MOSFET's connected in parallel if ups is t work longer than expected.
Then it comes to charge current you have to adjust to get batt
