Simulation Solar Power Regulator On Bread Board and Multisim

Objective:

1. To find the output value from both of methods
2. To distinguish between the both of circuit methods
3. To ensure the project works
4. To learn how that project work
5. To find the potential problem

Procedure:

• STEP 1

1. Step one is to construct the circuit by using bread board
2. Prepare all the component that use in solar power regulator
3. Construct the circuit following the schematic that prepare
4. Make sure the terminal and polarity of each component is correct to connect
5. Battery 9 volt used in that circuit to replace solar panel
6. After finish construct the circuit, double check the flow of circuit before running
7. The circuit run and to check the output voltage use the multimeter
8. Multimeter set on Dc voltage position.
9. Put the probe to the output of circuit, and reading from the multimeter record.

• STEP 2

1. Step 2 is to simulate the solar power by using Software Multisim 2001
2. Open the software, and than create a new project 
3. Select all component that listed on schematic circuit
4. Construct the circuit following the schematic of solar power
5. In this multisim also used 9 volt battery
6. check the output voltage by using multimeter or voltmeter in Dc.
7. Data record from the output value.

Data record

1. On bread Board = 2.44 volt
2. By using Multisim = 2.087 V

Analysis:
 From both value there have a different output value of voltage. It is maybe that cause by battery that use in bread board less than that required. It also the component that use is not match from schematic. After battery disconnect we can see the circuit still shown the output voltage.
From here we know that the capacitor 1 farad keep the charge. 

Conclusion :
to find the correct value of output voltage, we should use the correct component.

Circuit Troubleshoot

Objectives:

1. Troubleshoot the short circuit after do the itching process
2. Troubleshoot the open circuit after do the itching process
3. To prevent short circuits when soldering components 

Procedure:

1.  After itching process is finished, testing do by to check the open circuit and short circuit.
2. There we use a multimeter the check the circuit.
3. On multimeter set it on 20 kilo ohm.
4. Connect red and black prob to the multimeter. Test a meter to make sure it working.
5. Touch the probe to the circuit and look at the indicator meter.
6.  If the circuit is broken, the circuit should be connected by using solder.
7. Then check the circuit again using multimeter.
8. If the circuit in short circuit, disconnect with a knife or any material.
9. Then check the circuit again using multimeter.
10. Schematic circuit is used as a reference during a test
11. Do the process until error vanish 

Analysis:

In this case, circuit we only have problems in short circuit and have no problem at open circuit. This is because, when printing on paper, sketch too close to the circuit between the connection. To solve that problem testing do and and which circuit have a short, it disconnect with a knife or any material. 

Conclusion:

Testing is very important to be done on the circuit after the itching or any wiring done at the circuit. This is to ensure that the circuit is in good condition and to avoid problems when the components is soldering.

P.C.B Board Itching For The Solar System

Objective: 

1. Preparing to construct the circuit by using P.C.B board
2. To make the arrangement of component before make a soldering

Procedure:

1. Photocopy the PCB layout (In Previous Report) in to  sheet using laser printer    
2. Attach the paper on the P.C.B board. The P.C.B. board avoid exposure to light.
3. Put transparent paper sheet and the photo-etch board into a UV exposure unit for 60 second.
4. Wash the developing using ferric chloride. Let the P.C.B in the acid and shake it till the circuit clear from copper that not needed on a board.
5. Transfer the PCB in to etching tank and do the operation for 4 minutes.
6. After finish on etching tank, scrub the P.C.B board using sand paper
7. Make sure the connection of PCB is in right continuity. 

Result and analysis:

• All the process of producing the PCB is done step by step
• To make sure circuit connected do the testing to circuit by using multimeter

Conclusion:

The method are used in this PCB process are essential so that no important steps are skipped. Skipping any of these may cause failure to the outcome of the project. The steps are done is to helped us troubleshoot the hardware and software if any complications should arise

Preparing To P.C.B Board Entching

Objectives:

1. To prepare the circuit before
2. To make the P.C.B layout
3. To confirm that p.c.b solar layout
4. To make sure that p.c.b layout correct before do the etching

Procedure:

1. Here we have two choice. First, design the P.C.B by using software(Diptrace). Second, by using p.c.b layout from magazine.
2. To facilitate the design process of making p.c.b circuit layout, there are examples in the magazine was edited according to the size needed   
3. Original size and shape to the left magazine during edit on the p.c.b circuit sizes must follow to determine what was in the magazine. This is to prevent the components such as IC can not enter.
4. Width of the circuit that edit or sketch is 38 mm. while the circuit is 51mm long.
5. After the editing process is made, the circuit print on the A4 paper. Double check circuit.
6. If the circuit was not clear print, color the circuit to avoid the circuit is broken when the circuit is print on transparent
7. After this process is complete then print paper had made ​​photocopy to the transparent paper.
8. If there have a problem on the transparent paper repeat the process for the second time. 

conclusion:

After all this process is made and has resulted in a complete p.c.b layout and all according to what is required then the next process can be done. The process is the process of etching the solar power   circuit
