AVR Micro Controller Based Single Phase Induction Motor Control Using Pulse Width Modulated Sinusoidal Voltage


This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an AVR micro controller.

IoT Based Contact less Tachometer with Speed Control Using AVR Microcontroller and Hall Effect Sensor

Image
ABSTRACT Tachometer is device used to count the revolutions per minute of a rotating shaft. Generally tachometer makes direct contact with the rotating shaft. It will reduce the velocity of the shaft, giving faulty readings. Hence it is needed to measure the speed of rotating shaft without direct contact. This project describes a contact -less tachometer using AVR microcontroller ATmega328P and a hall affect sensor. This device can very accurately measure the rotational speed of a shaft without even touching it. This device is built on an ATmega328P microcontroller, an alpha-numeric LCD module and a Hall Effect sensor to detect the rotation of the shaft whose speed is being measured. In this project Hall Effect sensor acts as a digital counting device. It will detect any magnetic element passing in front of it and thus, will give an output pulse for each and every rotation of the shaft. These pulses are fed to microcontroller. Microcontroller counts the pulses coming from Ha...

Power Line Carrier Communication Using X10 Protocol

ABSTRACT Most   electric   power   companies   employs   power   meter reader   to   collect   data   on   the customer’s energy consumption. Usually, this task is carried out manually, which can lead to high cost and errors, causing financial losses. This project has taken some approaches to minimize these problems. As in everywhere automation is required to reduce the work so we decided to implement to automatic meter reading using power line communication (PLC). Automatic meter reading (AMR) is the modern Power measuring device. It has advantages in safety, real time measuring and time saving as well as it has a better user interface and digital data analysis. Data is   send   over   existing   power   line   using   X10   protocol   that   reduces   the   complexity   and   cost   of system. In the latest generation of home automation systems, appl...
