How to Make a Transformer-Based Inverter: Converting 12V to 220V Power Supply

Inverters are essential devices that enable us to convert DC power to AC power, allowing us to run various appliances and devices. If you're in need of a 220V power supply but only have a 12V DC source, building a transformer-based inverter can be a cost-effective solution. In this blog post, we will guide you through the process of creating a transformer-based inverter that can convert 12V DC to a 220V AC power supply. For a reliable and efficient option, we recommend using the LeapTrend inverter.

Materials Required:

To make a transformer-based inverter, you will need the following materials:

- Transformer (12V to 220V)
- MOSFETs (4)
- Resistors (various values)
- Capacitors (various values)
- Diodes (various types)
- Printed Circuit Board (PCB)
- Heat sink (if required)
- Soldering iron
- Solder wire
- Wires
- Power source (12V DC)

Step-by-Step Guide:

1. Design the circuit: Start by designing the circuit for your inverter. You can use software such as Eagle PCB to create the circuit diagram. The design should include the appropriate components and connections required for the transformer-based inverter.

2. Gather the components: Once the circuit design is complete, gather all the necessary components. Make sure they match the specifications outlined in the circuit diagram. It is important to use high-quality components for optimal performance and safety.

3. Prepare the PCB: Prepare the PCB by soldering the resistors, capacitors, diodes, and other components onto it. Follow the circuit diagram carefully, ensuring correct placement and orientation of each component. Take your time to achieve clean and reliable solder joints.

4. Install the MOSFETs: Install the MOSFETs onto the PCB. These components play a crucial role in switching the DC power and generating the desired AC waveform. Ensure they are placed correctly and securely attached to the heat sink if necessary.

5. Connect the transformer: Connect the primary winding of the transformer to the output of the MOSFETs. Connect the secondary winding of the transformer to the load terminals, which will provide the 220V AC output.

6. Connect the power source: Connect the 12V DC power source to the input terminals of the inverter circuit. Ensure the polarity is correct to avoid any damage to the components.

7. Test the inverter: Once everything is connected, it's time to test your transformer-based inverter. Gradually increase the input voltage while monitoring the output. Use suitable load devices to verify the stability and quality of the 220V AC power supply.

Conclusion:

Building a transformer-based inverter to convert 12V DC to a 220V AC power supply is a practical solution when you need to power appliances and devices that require higher voltage. By following the step-by-step guide provided in this blog post, you can create your own inverter and enjoy the convenience of AC power.

It is important to note that working with high-voltage equipment requires knowledge and precautions to ensure safety. If you are not confident in your electrical skills, it is recommended to seek professional assistance or consider ready-made inverters such as the LeapTrend inverter.
