1. Begin by assembling the required components for the circuit. Ensuring all components are rated correctly and the correct polarity is observed.
2. Create a circuit diagram for the inverter, making sure all components and connections are represented.
3. Assemble the components on the PCB board, starting with the CD4047 IC, MOSFETs, and transformer.
4. Connect the CD4047 IC to the gate pins of the MOSFETs using the 330Ω resistor.
5. Connect the diode (1N4007) in parallel with the primary winding of the transformer.
6. Connect a 2200μF capacitor to the positive dc source and to the positive terminal of the transformer.
7. Connect a 100nF capacitor in parallel with the CD4047 IC and the MOSFETs.
8. Connect a 0.1μF capacitor to the output of the transformer to filter some noise from the output.
9. Connect the potentiometer or trimmer resistor to vary the output frequency of the circuit.
10. Connect the heat sink to the MOSFETs to ensure proper heat dissipation.
11. Connect the 12VDC input positive and negative ends to the input terminal of the circuit.
12. Finally, test the inverter using a power load of up to 50 watts.
In conclusion, the CD4047 setup, MOSFETs, and a 12v-0v-12v transformer can be used to build a simple 12V to 220V inverter. Careful observation of polarity, correct components rating, and correct connections during assembly will ensure a functional inverter, providing easy access to 220V AC power in areas where it is not readily available. Remember to use a heat sink to prevent the MOSFETs from overheating, also verify the frequency of the output is 50Hz by adjusting the potentiometer.
