Hello everyone, I am looking for a very good schematic for a 100amp to 200amp CONSTANT CURRENT PWM with a 12vdc to 15vdc range.

Can anyone help me

How is the current constant if it is pulse-width modulated?

Do you mean where the average current is constant?

That's easier said than done since even small inductances will make holding average current tricky.

What are your performance specs? In other words, how "constant" (on average) is "constant enough"?
