How to Control the SCR with Microcontroller. I dont want to mix the Digital Signal Ground with the High Voltage Ground. But the SCR will need the Gate current in uA w.r.t its Cathode. But I couldnot connect the Cathode of SCR to the control circuit..

Help me a correct Triggering Circuit for SCR on the Bridge Rectifier. #bridge-rectifier #phase-control

Hello

A recent Application Note answers you.

AN4606 : Inrush-current limiter circuits (ICL) with Triacs and Thyristors (SCR) and controlled bridge design tips

=> See section 2. Control circuits.
