Project Idea:
This project demonstrates a thyristor-based dual converter system to control the direction and speed of a DC motor. It converts AC to DC using controlled rectification, allowing polarity reversal via forward and reverse bridges. A microcontroller triggers SCRs to gradually control speed, making this ideal for power electronics and motor control learning.
