hi everyone iam trying to design a heater controller for industrial purpose (11kw) using arduino and some components the design diagram is attached bellow ,the wcs1700 current sensors used to monitor the currents of 3 individual 230v dc (igbt g60n100bn) in safe level,load is connected on collector side(is it ok?),iam a beginner in power electronics and arduino,am forgot to include the LCD display block on diagram, help me to guide this project

 

Your attachment missing ?

 

Your attachment missing ?

SORRY THIS IS THE ATTACHMENT......

 

My feeling is this is way above a beginners project. It sounds quite leathal.
Please be careful, and better yet, get some local qualified help before you kill your self.

THANKS ...,but am turned on (approx 16a 230v dc heater ) using 555 pwm and lm 324 opam (using 4 to 20 ma signal) here arduino and all the setup is connected in proper way??what are the precautions i need to take to protect the igbts

 

I would google "high power high current circuit design safety" and spend
some time reading the safety practices info.
