I am a college student and I would love to make a 3 phase fully controlled rectifier circuit as my project. I need the circuit diagram of the firing circuit for the 3 phase rectifier circuit. Will you please help me out.

This is a complex and challenging project for someone with limited experience. One can purchase pre-built SCR firing control boards for AC-DC converter work. These cost a good deal of money. Building from scratch will be a long term project.

In addition if you are planning to do something with hazardous AC mains power then we have to be careful as to the advice we provide you with.
