Hello,

I have this schematic that uses outdated electronics. My assignment is to renew this schematic but i want to keep everything after the mosfet's. The input is 5V PWM signal. Does anyone know a part of the schematic i can replace with an IC. An Ic that contains a MOSFET Driver with feedback would be perfect but can't seem to find one. I already know how this schematic works but i need help to update to modern electronics.
(sorry for my english)

Thanks in advance

 

this is for a welding machine btw.

 

There is the pld Motorola MC33030 DC motor controller with F.B. that may do the job.
Max.
