Analog-controlled thyristor 3-phase rectifier

[jaro1]

Hello, I have a transformer with a primary of 3x400v, a secondary of 3x42v, does anyone have a schematic of a analog controlled thyristor rectifier?

Your question is vague. What is your application? Do you wish
half-wave controlled, full-wave controlled
or free-wheeling rectification?

What is your application? Why do you need a thyristor controlled rectifier instead of a simple 3-phase diode bridge?
