PROJECT DESCRIPTION

The main aim of this project is to design a power-electronic converter which is used to change the polarities of a DC supply from available AC to control a DC motor in both directions.

The proposed system uses a microcontroller of the 8051 family and a rectified-power supply.  The thyristors are interfaced to the microcontroller throughOpto-isolators for switching the load by delaying firing angle for speed control. The motor direction is selected by the push button switches, which is interfaced to the microcontroller.  The Opto-isolator is used for isolating signal circuit power to mains power .

This project uses two thyrisitor controlled bridges(4 SCRs X 2 ), which are used to change the polarities by pressing corresponding switches. Microcontroller triggers each bridge of SCRs according to the program to change the direction of the DC motor by reversing the DC polarities.
