capacitor to overcome voltage source limitation [closed]

This question cannot be answered in its current form, because critical information is missing.

This question was closed; new answers can no longer be added. Users with the reopen privilege may vote to reopen this question if it has been improved or closed incorrectly.

Hello,i need to drive 5 mosfets as shown below. Each mosfet draws 15A when the pulse opens the mosfet. My power supply is gives the 48V but only 3.3A,If I understand correctly I need to put very high decoupling capacitors at the voltage source so I will have in that short period of time the 5*15=75A .

My V4 power supply in real life can supply only 4A as shown in the link and datasheet below. When i put a 10uF capacitor i cant see any higher amount of current. how do i properly simulate this capacitor phenomena In LTspice Thanks.

I closed this question because it was too sloppy. We do engineering here, which includes attention to detail. I gave up at the second "i". You talk about 5 FETs, but I only see 3. The schematic is very hard to read because it's so small. Certainly you can see this for yourself. You could easily have drawn the schematic so that it wouldn't get shrunk to oblivion.

There will be no answers for you until you fix this mess and stop thumbing your nose at the volunteers here.

yefj‭ What's the purpose of this device? What do you ultimately need to accomplish? The question is missing the context.
