2. INTRODUCTION
• The field of energy conservation is becoming an increasing notable
subject of research among the scientific community today
• The aim of the proposed system is to use the mechanical energy
produced during cycling in order to generate electricity
• The system leads a way to preserve our environment and reduce
pollution
3. PROPOSED SYSTEM
• In the proposed system we are using the exercising cycle equipment
for electric power generation.
• In this the electric power is generated even though in the absence of
sunlight
4. ELEMENTS
• It consist of the following elements;
1. Prime mover
2. Generator(Alternator)
3. Battery
4. Rectifier
5. Inverter
6. Transformer
6. • From the prime mover the mechanical energy is given to the
synchronous generator
• The generator generates 12V,10A Ac output.This Ac Output is
obtained by regulation process and it is given to the rectifier
• Rectifier converts the AC output to DC output this converted DC is
stored in the battery
• From the battery the DC is used for excitation in one hand and also is
given to the inverter circuit in order to produce AC for the load
7. • The load is lighted,when the output from the inverter being 12V AC is
stepped up to approximately 230V Ac
• When the prime mover is not providing the mechanical input the
230V AC main supply is taken and is given to the step down
transformer
• The stepped down AC is then rectified and stored in the battery and
the inverter functions the same leading to load
8. PRIME MOVER
• The mechanical energy is given by the exercising cycle to the
alternator through chain and belt drive
• The spinning motion of the tyre is used to produce mechanical energy
which is directly given to the alternator
9. ALTERNATOR
• An Alternator is a device that converts mechanical energy in to
electrical energy in electricity generation
• A three phase 750w,220V,50Hz permanent magnet alternator is used
to generate electricity from kinetic energy
• Around 2500-3000 RPM Is the output current begins reach to itha
maximum potential
10. ALTERNATOR OVERVIEW
The alternator contains,
• A rotating field winding called the rotor
• A stationary induction winding called stator
• A diode assembly called the rectifier bridge
• A control device called voltage regulator
• Two internal fans to promote air circulation
11.
12. BATTERY
• An electric battery is a device consisting of one or more
electrochemical cells that convert stored chemical energy into
electrical energy.
• The battery is a two terminal device that provides DC supply to the
inverter section when the AC mains are not available.
• The battery we are using here is 12V,10A rating.
13. RECTIFIER
• The rectifier circuit is a circuit which converts the AC supply to DC
output.
• Six or eight diodes are used to rectify the AC stator voltage.
• Two diodes are connected to each stator lead. One positive the other
negative.
• Because a single diode will only block half the AC voltage to DC
voltage.
14. TRANSFORMER
• A transformer basically is very simple electrical device that works on
the principle of Faraday’s law of induction.
15. • A transformer converts electrical energy from one value to another.
• There are two types of transformers step-up and step-down
transformer.
• The step-up transformer converts the lower value of voltage into a
higher value.
• The step-down transformer converts the higher value of voltage into a
lower value.
16. LOAD
• Load is the generic term for something in the circuit that will draw
power.
• Anything that uses electricity to do work will draw current.
• The amount depends on how much resistance to current flow the
device has and the amount of voltage applied to it.
• Here we are using a 40W incandescent lamp as load.
17. WORKING
• In electricity generation, a generator is a device that converts
mechanical energy to electrical energy for use in an external circuit.
• The project is based on generation of electricity while cycling The
cyclist when cycling will not be able to peddle at constant speed all
the time.
• Thus the belt arrangement is given to the wheel of the cycle to
provide constant input to the generator.
• Thus the mechanical input given to the generator is regulated by
using the voltage regulator, and maintained at a consant Value
18. • Thus the generator output will also be a constant AC.
• The AC output from the generator is given to the rectifier circuit to be
converted to DC.
• Thus converted DC output from the rectifier circuit is stored in the
battery.
• When the cyclist is not peddling the supply from the AC mains that is,
the 230V supply is stepped down to 12V AC and is then rectified to
12V DC and stored in a battery.
19. • This supply from the battery maybe used by the inverter circuit to
light a load when the cyclist is not peddling.
• On the other hand the DC stored in the battery during the first cycle
is used by the inverter in order to light the load.
• The inverter circuit is a circuit that converts the12V DC input to 12V
AC output.
• The AC output from the inverter is stepped up approximately to 230V
and is then given to the load.
21. DISADVANTAGES
• Low energy production
• Battery maintenance
• More space requirement
• High noise
• Initial cost high
22. CONCLUSION
• This project is aimed to preserve our environment from various
effects of different methods of power generation.
• This helps in reducing the electricity bill in homes.
• This equipment may be used to light any of the small equipments in
our homes.
• This equipment is eco-friendly and reduce environmental pollution.
