ABSTRACT
With the existing push in the direction of sustainable, clean sources of power, it is no
and available everywhere, the power of the sun can be employed to power everything like cell
phones and MP3 player. The sun's energy is usually harvested through solar panels that are made
up of photovoltaic cells. These cells can convert the sun's power into electricity that can be used
for a number of purposes. For private use, a handheld solar hybrid charger can be employed to
recharge little device for instance a MP3 player, a cell phone, or a camera.
A normal PN junction diode is used for unidirectional flow of charge current. The output
of the solar panel depends on the intensity of the solar light. Use of embedded technology makes
this system efficient and reliable. Micro controller (AT89S52) allows dynamic and faster control.
Liquid crystal display (LCD) makes the system user-friendly. AT89S52 micro controller is the
heart of the circuit as it controls all the functions.
In this project the usage of solar energy by using solar panels are used .A voltage sampler
is interfaced with the system to get the voltage generated on a 16X2 LCD.
An alternative charger circuit is also provided to charge the mobile by house hold general
purpose 230V in the absence of the sun light. This charge circuit uses regulated 5V, 750mA
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 230/18V step down
transformer.
