Solar Electric Charge Controller and Portable Power Supply

Solar Electric Charge Controller and Portable Power Supply projects main aim is to develop a micro controller based device which will use solar energy to recharge a DC battery. In order to setup this system solar panel should work at an optimal power. In order to generate maximum and consistent power from solar panels controllers will vary voltage across the solar panel. Here we use pulse width modulation techniques to charge the DC battery by maintaining voltage level. 

The main electronic components of our product are the solar panel which provides power, generated power is supplied to rechargeable batteries, Circuit is used for improving power sharing between two,and a LCD and two LEDs as outputs to the user.microprocessor  For loading program on to PIC18F452 chip we use serial port and receive data output on a terminal program (such as HyperTerminal). 

Hardware used in this project:

  1. DC DC converter
  2. PIC Micro controller
  3. Micro chip for current sensing.
  4. LCD Display.
  5. Serial port for communication.

Single Dc Motor Speed Control By Tv Remote

Abstract:– Here is a very simple example of DC motor speed control by changing firing angle of TRIAC with the help of micro controller AT89c52.In order to mange speed variations for the motor we use firing angle by using thyristor. This method is widely used method for speed variations in DC motor systems. In this project we use AT89C52 controller in the place of DIAC for firing TRIAC.A zero crossing detector circuit is used here to interrupt AT89C52 after every 10 ms. After getting an interrupt AT89C52 will fire TRIAC after some delay from 1 to 9 ms. This will reduce the current input to motor and so the motor speed will reduce.By changing the delay time with the TRIAC speed variation can be managed.

Software logic: –The complete operation is based on the software embedded in micro controller P89C51ED2.C is the programming language used in this application. Each function written has different functionality like ext1,ext2 and delay in speed. Programmed code is written on to micro controller.

Energy Saving Systems For Railway Platforms

Energy Saving System For Railway Platforms Projects main idea is to develop a micro controller based project for saving energy for railway platforms.

NEED FOR THE PROJECT: Normally in railway platforms Whether the Train is there or not, Unnecessarily all Lights in the platforms are Glowing.  In present system there is lot of usefulness wastage of energy. Maximum energy is wasted at the time of no train on the platform. All the lights televisions etc are not stopped when there is no use.

AIM OF OUR PROJECT

Our project is a computer controlled system Wherein all the train arrival and departure timings are entered in it. 

So we can able to switch on all the lights When the train is about to come or to leave.  During the other times we can glow Some important lights so that the platform will not be left completely dark.

In this project micro controller application setup is installed at each platform. Using a remote PC we will command micro controller unit for controlling lighting system for each platform.

Ac Induction Motor Speed Control Using Constant V/F Method.

AIM:    AC Induction Motor Speed Control Using Constant V/F Method projects main aim is to develop a micro controller based speed control application using variable frequency control method. This project is a simple application which can be done with a low cost.

With a cost effective process it is easy to control AC induction motor using one of the most popular voltage frequency ratio technique.

Description:  In present scenario each and every industries are using DC motors, reason behind this is it is easy to control the speed of DC motor compare to AC motors. But there are few drawbacks in DC motors compare to AC motors.

Maintenance for DC motors are more compare to AC motors.  By introduction of power electronic devices DC motors are replaced with AC motors because speed control problem had solved with power electronics devices.

In this paper we will cover how power electronic devices works with induction motors and we explain in detail about supply frequency and many other factors.

Automatic Ac Light Control Using Triac

AIM:            The main aim of Automatic Ac Light Control Using Triac project is to design equipment by which an AC light control is obtained automatically by using TRIAC.

Description:          In this project the major part considered here is the passive infrared sensor. Passive Infra Red sensors are mainly used for sensing radiations that are radiated by objects in its field of view. PIR sensors are used in many application like motion detectors . These sensors radiations are not visible to human eye but it can be detected by electronic devices. This sensors can detect temperature variations of the object which is moving in front of it. It works on black body radiation.

This passive infra red sensor is human detection sensor. when this pir detects the human movement it immediately sends signal to the micro controller. So from the microcontroller a signal is sent to the opto coupler and triac is activated.so by this the AC bulb is made on. Here the LCD displays whether the bulb is in ON condition or OFF condition. Hence the ac light control is obtained automatically using triac.

Automatic Power Meter Reading System Using Gsm Network

AIM:Automatic Power Meter Reading System Using GSM Network projects main aim is to improve the method of monitoring and recording the power meter. This application uses GSM technology which is used in mobile communication. Using this application power meter reading will be sent to user Mobile number through SMS using GSM technology.

DESCRIPTION: In present generation usage of technology had grown to a higher extent in every field. But there are many fields automation is still to be done one among them is power meter reading system. This system will provide automation and high security. In this system we use GSM mobile communication technology for sending power meter reading information to users through SMS(short message service).

In present situation there is no automation process. We need to go to e-seva or electrical department for paying bill which is a time taking process. This project will provide security and secure transaction methods which will decrease mismatching cases. In this paper we will explain in detail using block diagram.

Prepaid Energy Meter Using Smart Card

AIM:Prepaid Energy Meter Using Smart Card Projects main idea is to develop a micro controller based application which is used to pay bills using a smart card technology.

PURPOSE: This project will focus on overcoming the past procedure of electricity bill payment methods by using smart card technology. This system will provide reliability and increase security.

Description:        In present scenario electricity bill payment can be paid at e-seva or substations. This process is a time taking and risky process. Using new smart card method payment process will be fast and time saving. Electricity bill can be paid using prepaid electricity billing system. This system works on smart card technology.

Smart card is similar to that of SIM card which should be recharged same as that of mobile recharge card. Based on the usage of power we need to recharge the card by placing it in the card reader. Card reader is interfaced with the micro controller using a serial interfacing. While recharging it will ask for how much of power consumption we need to use in KWH. This information is displayed on the LCD screen.

Speed Control Of D.C Motor Using Thyristor Dual Converter

Speed Control Of D.C Motor Using Thyristor Dual Converter projects main idea is to implement a micro controller based application for controlling speed of the D.C motor using a dual converter. Main use of dual converter is to easily change the direction of the motor and handle braking system of the motor. This application works on single firing unit and firing pulses, this unit is diverted by converter using a main controller which is also called as master controller.

This application works on three control loops.

  1. One for controlling armature current control.
  2. Second is for adjusting firing angle of oncoming converter.
  3. Third loop is used for speed control.

In order to provide steady state response and efficacy of the system we use proportional pulse integral type of converters.
