Speed of Ac motor is controlled by a thyristor. And the thyristor gate pulse is controlled by The pwm of uController. A user password is there to unlock. To change user password an Admin. Password is needed. If 3 times wrong password is entered then system needs the Admin. Password. Total current over the supply is same. So we will measure how much current is used per home and there sum should be same (approx.) as the supply current Underground cable supply. Power failure identification. Each home supply is controlled at system room. Extra power taken by the home traced. Supply beneath the ground may suffer fault. Which is traced and displayed by LCD In a power supply system over current and over voltage is traced an powers supply is varied or stopped Proportional-Integral-Derivative tuning is used For a constant voltage supply. Supply o/p may be buck or boost Control your stepper motor based devices by controlling direction and speed. Control your stepper motor based devices by controlling direction and speed.
