Hi
My objective in this project is to control the speed of an ac induction motor by varying the frequency
using SCRs that form the cycloconverter.
Triggering gate pulses for each SCR are generated by the micocontroller as per the code written.
The PROBLEM i have is that the SCRs conduct even with no pulse at their gate. i Need a control circuit for triggering these SCRs.
Here is my proteus design;
