MPPT SOLAR CHARGE CONTROLLER Well, The most advance solar charge controller available in the market is Maximum Power Point Tracking (MPPT).The MPPT controller is more sophisticated and more expensive.It has several advantages over the earlier charge controller.It is 30 to 40 % more efficient at low temperature.But making a MPPT charge controller is little bit complex in compare to PWM charge controller.It require some basic knowledge ofpower electronics.
What Is MPPT ?
The Maximum Power Point Tracker (MPPT) circuit is based around a synchronous buck converter circuit..It steps the higher solar panel voltage down to the charging voltage of the battery. The Arduino tries to maximize the watts input from the solar panel by controlling the duty cycle to keep the solar panel operating at its Maximum PowerPoint.
The Maximum Power Point Tracker (MPPT) controller increase charge current by operating the PV module in a manner that allows the module to produce all the power it is capable of a conventional charge controller simply connects the module to the battery when the battery is discharged. When the 75W module in this example is connected directly to a battery charging at 12 volts its power production is artificially limited to about 53 watts. This wastes a whopping 22 watts or nearly 30% of the available power! Patented MPPT technology used in this MPPT controller design operates in a very different fashion. The MPPT controller continually calculates the modules maximum power voltage, in this case 17 volts. It then operates the module at its maximum power voltage to extract maximum power. The higher power extracted from the module is then provided to the battery in the form of increased charge current. In conditions where extra PV power is not available, Sigma MPPT controller will operate as a conventional controller with very lowvoltage drop.
THE MOSFET DRIVER
A Mosfet driver allows a low current digital output signal from a Microcontroller to drive the gate of a Mosfet. A 5 volt digital signal can switch a high voltage mosfet using the driver.A MOSFET has a gate capacitance that you need to charge so that the MOSFET can turn on and discharge it to switch off,the more current you can provide to the gate the faster you switching on/off the mosfet, that is why you use adriver.
For this design I am using a IR2104 Half Bridge driver. The IC takes the incoming PWM signal from the micro controller, and then drives two outputs for a High and a Low Side MOSFET.INPUT :
First we have to provide power to the gate driver.It is give on Vcc (pin-1) and its value is in between 10-20V as per data sheet. The high frequency PWM signal from atmega ic goes to IN (pin-2) . The shut down control signal from the atmega ic is connected on SD ( pin3).
OUTPUT :
The 2 output PWM signals are generated from HI and LO pin. This gives the user the opportunity to fine tune the dead-band switching of theMOSFETs.
CHARGE PUMP CIRCUIT : The capacitor connected between VB and VS along with the diode form the charge pump.This circuit doubles the input voltage so the high switch can be driven on. However this bootstrap circuit only works when the MOSFETs are switching.fig1.2:

* Unzip the .rar file. * Run the file Proteus Professional 8.5 – SP0 – DEMO.exeand follow the installation instructions. * During installation select the license locally, using the file License Key.lxk. A license manager window should appear. Use Browser for Key Fileto load the license and Installto install it. * Finally, run the file Update Proteus 8.5 SP0 DEMO to PRO.exeto unlock the demo version. In the address field, look for the folder where the Proteus has been installed, it is usually: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional.

WEDNESDAY, 31 JANUARY 2018 SIMPLE CAR TRACKER WITH ATMEGA328A SIMPLE CAR TRACKER WITH ATMEGA328ACOMPONENTS NEEDED:
1. ATmega328
2. Sim300 gsm module 3. GY-GPS6MV2 gps module 4. Android smartphone5. lcd 16x2
6. back_up battery
Here in this system we are using the GSM module for sending the coordinates of vehicle on mobile phone via message. GPS is sends the coordinates continuously in form of string. After reading this string using Arduino extract the required data from string and then sends it to mobile phone using GSM module via SMS. This information is called latitude and longitude. GPS used 3 or 4 satellite for tracking the location of any vehicle.Circuit diagram

HEART BEAT PROJECT USING ATMEGA328 HEART BEAT PROJECT USING ATMEGA328P PROJECT DESCRIPTION: HEART RATE, BODY TEMPERATURE AND BLOOD PRESSURE MONITORING ARE VERY IMPORTANT PARAMETERS OF HUMAN BODY. DOCTORS USE VARIOUS KIND OF MEDICAL APPARATUS LIKE THERMOMETER FOR CHECKING FEVER OR BODY TEMPERATURE, BP MONITOR FOR BLOOD PRESSURE MEASUREMENT AND HEART RATE MONITOR FOR HEART RATE MEASUREMENT. HERE WE HAVE USED A HEARTBEAT SENSOR MODULE WHICH SENSES THE HEARTBEAT BY THE PULSE IN EAR, HEART RATE EAR CLIP KIT CONTAIN A EAR CLIP AND A RECEIVER MODULE. THE HEART RATE MEASURE KIT CAN BE USED TO MONITOR HEART RATE OF PATIENT AND ATHLETE. THE RESULT CAN BE DISPLAYED ON A SCREEN VIA THE SERIAL PORT AND CAN BE SAVED FOR ANALYSIS.
