Any one help me a circuit mosfet gate

I built an inverter using sg3525 it work with most of my appliance
but i can use it with my laserjet1018 hp printer and also
my freezer.
I try add more 3205 mosfet but still cannot run and also i try and built big transformer
but still voltage drop and can't let my laser printer and freezer work.
But, all other appliances is work efficiently even including 1000watts electric iron.
recently i bought 2000watts modified sine-wave from china it able to power them all.
But, i still fill to use one that built by my self wow!
I open it and found-out that thier own is work by mosfet gate driver.
Is any one here help to achieve my aim!

Post a schematic of your home-built inverter and perhaps we can help.

If your circuit is working properly then your issue mighty be surge current, a compressor type fridge will take a larger inrush current.

You can get mosfet gate driver ic's, take care if using one of these pcb track layout is critical, I've fried a couple.
