Hi.

Your drawing is not triac's but thyristors. A triac symbol looks like this.

Do you intend to use triacs or thyristors?

Is the supply voltage AC or DC ?
 

Hi waqas ikhtiar ,

Look examples on end of manual for TCA785:
**broken link removed**

For full bridge rectification diagonal thyristors must be triggered in same time.

Best regards,

Mr.Cube
