Automatic active phase selector for single phase load from 3 phase supply

POWER DEVICES OPERATED THROUGH MOVEMENT SENSOR

ABSTRACT:

In this project we are controlling the power devices by using MEMS Technology. In this project we are control the devices by using MEMS technology. In MEMS we have Tilt register. When we change the direction, the tilt registers values are changed and that values are given to microcontroller. Microcontroller compare this values and depend up on option occurred it control the power devices. Here by using mems, we can able to control the device switching by each value we get using mems we send to controller there it compares and according to input the devices can on/off.This project uses regulated 5V, 500Ma power supply, 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.BLOCK DIAGRAM:-
