Electric Converter It is a type of machine used for converting

electrical power to different levels according

to the needed energy the device that isconnected to it requires.

It uses the concepts of electric power

conversion, Faradays Law ofElectromagnetic Induction and Energytransformation.

Electric Power ConversionIn electrical engineering, power conversion has a

more specific meaning, namely converting electricpower from one form to another. This could be assimple as a transformer to change the voltage of ACpower, but also includes far more complex systems.The term can also refer to a class of electricalmachinery that is used to convert one frequency ofelectrical power into another frequency.

Power conversion systems often incorporateredundancy and voltage regulation.

Construction Procedure First, Connect the resistor, Capacitors, diodes and the

Transformer using the connecting wires. Thenconnect this to the switch.

Then, create the wooden box that will serve as yourcontainer. Place the electrical converters main partsinside the wooden box. You may use a screw to

tighten the converter. Connect the plug and the alligator clips to the

converter. Afterwards, connect the clips to the load.

Test the converter.

Manual Operating Procedure 1.)Connect the electric plug to the socket. 2.) Check if the indicator light works.

3.) Connect the alligator clips to the selected load. First the fan.

4.) Turn on the switch to the desired voltage. Check the work produced by the fan.

5.) You may increase the voltage as desired and as long as the load can take it.

6.) Turn of the Main Switch.

7.) Try connecting the alligator clips to the light bulb. Then turn on the switch ofthe light bulb. Turn on the Main switch to desired voltage and check the lightproduced by the light bulb.

8.) Turn of the Main switch again.

9.) Connect the alligator clips to the dynamo. This will create grater amount ofwind.

10.) Do the same to the dynamo. (But be careful in leveling the voltage because somedynamos might not be able to take 12 volts.)

11.) You may also try connecting the Alligator clips to other devices.

Concepts in Physics Faraday's law of induction is a basic law of electromagnetism

relating to the operating principles of transformers, inductors, andmany types of electrical motors and generators.The law states that:

The induced electromotive force or EMF in any closed circuit is equal

to the time rate of change of the magnetic f lux through the circuit. Or alternatively: The EMF generated is proportional to the rate at which flux is linked. Electromagnetic induction was discovered independently by Michael

Faraday and Joseph Henry in 1831, however Faraday was the first topublish the results of his experiments. Expanding on Faradays work,

James Clerk Maxwell formulated the law quantitatively. Traditionally, two different ways of changing the flux through a circuit

are recognized. In the case oftransformer EMF the idea is to alterthe field itself, for example by changing the current originating thefield (as in a transformer). In the case ofmotional EMF, the idea is tomove all or part of the circuit through the magnetic field.

Advantages1. Converter may be used in different devices. It is used

as a medium for devices to work.

2. The converter is efficient and is user-friendlybecause of the different insulations in the wires.

3. It may be a good substitute for the sources ofdevices that need small voltage of electricity but a

lot of batteries to operate.


10/11

Disadvantages1. The converters materials are expensive

specially the transformer.

2. It is also difficult to construct specially theconverter itself because of the wiringconnections made.

3. It also need a socket where it can beconnected to.
