tca785 3 phase control

im trying to build a three phase half-bridge(scr-diode), please can anyone help me .
if possible i need some code examples and the schematics of the circuit .
thx u

three phase half bridge

I builded 4 years ago (15V 1000A galvanic machine) but I dont use mcu, I use 3 TCA785 for driving gates of scr's, and one opamp for generating reference voltage.

Any specific question you want to ask?

What type of load you have (resistive, capacitive or inductive)? What current. What for you need mcu? ...

thank you mrcube_ns
well im trying to do a 110V 90A ,on a capacitive load , a series of batteries got any schematics , in particular how did you used the op amp to generate your reference voltage .

I posted some pictures on this subject, so look schematics first then we can talk.
