SCR and Controller based three phase voltage control

Electrical and e;

In our day to day life we are using a lot many devices to satisfy our needs or to make our life easy and happy. Every device has a power supply, to work . And for the better functioning of the device it is necessary that the supply should be good without interuption. That is, it should provide a constant which is not only AC but also DC voltage. But this is impossible always. Due to many reasons there is a voltage fluctuation in the supply. This fluctuations in the supply voltage may cause the device to damage or make it work in an undesired way, which no one would desire.So the best alternative is to regulate the supply voltage. This is what we have tried to achieve here. Our project is using controller and SCR voltage control of three phase system.This project we provide the load with a constant supply voltage of 230 V AC., in spite of any variation or changes in the input voltage. The voltage regulation is achieved by SCR by controlling the firing angle to it so precisely that the load receives a constant supply. The voltage across the load is stepped down and provided to Analog to Digital Control. ADC will produce a digital signal corresponding to the input analog signal.
