WEEK 6

TITLE OF ACTIVITY : Pulse width modulation.

OBJECTIVES : 
-To understand the basic operation of the inverter.

METHODS :
-Make observations about the sources and basic functions.
-Collect all the details fit.
-Search data sheets on the internet.

PIN CONNECTIONS OF SG3526

RESULT :
-More on observation by our gathering data.


Analysis :
-The basic operation of the power
inverter is illustrated in Figure 1.
The SG3526 alternately switches the
current through the 12-V windings of
a mains transformer, the two central
ends of the windings having been
taken together and connected to the
positive battery terminal (+12 V). At
each switching action, the direction
of the current changes and with it
the direction of the magnetic field in
the transformer core. The result is a
square-wave(-like) alternating voltage
at the 230-V side of the transformer.





CONCLUSION :
-Initial data collection is finally finished.

WEEK 5

TITLE OF ACTIVITY : Search at hobby kit, google, and software for our project.

OBJECTIVES :
-To insert and use the software in our project and what material additions.

METHODS :
-Finding the right software and materials used in the project.
-Installing the software for circuit sketch project.
-Provide additional material for the final work.

Perspex board

Software brand 6.3.0

RESULT :

-The software we are looking for is very suitable for the project because it eases the work of drawing the circuit and the materials we use are also suitable.

ANALYSIS :

-When looking for software on the Internet, we stalled because we do not know how to download it. So we plan to find friends who have the necessary software. Then, we need to go  Jalan Pasar, Pudu to get it because of this that we know there is supply electronic components.

CONCLUSION :

-We use other methods to get the software and find materials place a bit far.

WEEK 4

TITLE OF ACTIVITY : Search and buy the component.

OBJECTIVES : 
-Finding paths shop that provides the necessary components.
-Meets the necessary components.

METHODS :
-After identifying the components needed, we moved to Jalan Pudu market because there are readily available electronic components.


RESULT :
-We managed to get the required components.

ANALYSIS :
-Not all parts store sells the things we need. We have to try to ask the stores that sell our requirements. We need a long time to come across as too many shops but without the requisite components are all complete.

CONCLUSION :
-We are still working on to get all the necessary components and finally succeeded.

WEEK 3

TITLE OF ACTIVITY : BRIEFING FINAL YEAR PROJECT.

OBJECTIVES : 
-To tell about the format that how to do for log book or blog, marks and schedule.
-To brief about the function of the project.

METHODS :
-Lecturer brief about the format were had change and concerned about to scoring to try the best.
-Lecturer tells all formats available on the website and emphasize grammar. Lecturer also told Madam Norliah at section 1 if had the problem about the format.


RESULT :
-The observation is obtained in a website is no filling of the new version format.

ANALYSIS :
-While waiting for the new format, we continue with the next plan as usual.

CONCLUSION :
-We always take info from time to time and get detail and information from FYP website and whose take FYP.

WEEk 2

TITLE OF ACTIVITY : Shows an example of a circuit diagram of the project to the project advisor.

OBJECTIVES :
-for more information and confirmation.

Method :
-We meet project advisor and show the example circuit diagram for discussion.

-Taking note of what should be looked into seriously.

RESULT :
- We have decided that's the appropriate project name is 12V DC to 230V AC Power.
-We make observations of what components are needed and find a shop that sells electronic components.
