WEEK 4: CIRCUIT PCB DESIGN / TROUBLESHOOTING

Objectives: 

• To make a circuit PCB etching and drilling.
• To Test a PCB Inverter circuit.
• To analyse the circuit performance.

Content / Procedure: 

• Prepare a material to do circuit etching.
• Do a component test. Collect an old component that have been used in order to reduce a cost.
• Try to do some test towards etching circuit to analyse the performance.

Result and Analysis:

• I'm done a construction for  High Current Inverter Circuit. The circuit is fly-back converter and using 555 timers as an controller.
• This testing part was done by using my old equipments that have been used during my studies.
• The circuit PCB design and the pictures during etching the inverter circuit was shown below:

MY HIGH CURRENT INVERT CIRCUIT PCB DESIGN

• This is a PCB Design which is including my HCIC (High Current Inverter Circuit) and 3 stage protections circuit that has been designed before. The width = 4500 and height = 3000.
• Most of the circuit testing has been done at the home to avoid wasted time. 
• I successfully, checked the etching circuit and the current input to run the circuit.The power supply are getting by the battery 12V, 35 A.
• There are no problem happen to inverter circuit during the troubleshooting was done.

Conclusions

• This is our own designed circuit combining 3 stage protection circuit with high current invert circuit (fly back type).
• The output current and voltage from the inverter are considerably accurate based on input capacity form the battery. The lamp, phone charger can be used by using the inverter output.
• The protection circuit need to be done because it involved high current and can risk a circuit component.
