but what is the use of pin no.1(sense).....?
Click to expand...

it's the gate input just like the 'base' in ur bipolar transister
it's where you conext your 1k resistor in that your circuit
 

you can usee isolated material for mosfet with heatsinl
to connect two mosfet to one heat sink
 

FROM: https://www.afiata.com/1500w-ups-circuit/

HEATSINK PLATEN: The required 1cm./5W will make it neccessary to use an Al. plate 5.5" X 6" X .125"Th. using the IRF44's (good choice too). Isolate them

1. I would avoid the LC and go with a 60Hz source MM5369. I noticed the 220VAC
so you are using 50Hz European. The Xtal can be tweaked to that when you set up.
