 How to Make a Simple 2500W Sine Wave Inverter using MOSFETs and JLCPCB

Inverters are invaluable devices that convert direct current (DC) power into alternating current (AC) power, making them ideal for a range of applications. Whether you want to power your appliances during a blackout or harness renewable energy sources, having a reliable inverter can make all the difference. In this blog post, we will guide you through the process of building a simple 2500W sine wave inverter using MOSFETs and JLCPCB. Remember, safety precautions should always be followed when working with high-voltage equipment.

Materials Required:

To build a simple 2500W sine wave inverter, you will need the following materials:

- MOSFETs (8)
- Capacitors (various values)
- Resistors (various values)
- Diodes (various types)
- Transformer (specific voltage and current rating)
- PCB (Printed Circuit Board)
- Soldering iron
- Solder wire
- Wires
- Power source (e.g., battery)
- Heat sink (if required)

Step-by-Step Guide:

1. Design the circuit: Begin by designing the circuit for your inverter. Utilize software such as Eagle PCB to create the circuit diagram. Ensure the design includes the appropriate components, such as MOSFETs, capacitors, resistors, and diodes.

2. Gather the components: Once the circuit design is complete, gather all the necessary components. Ensure they match the specifications outlined in the circuit diagram. High-quality components are recommended for better performance and longevity.

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 are crucial for converting DC power to AC power. Pay attention to their placement and orientation. If necessary, attach heat sinks to the MOSFETs to dissipate heat effectively.

5. Connect the transformer: Connect the transformer to the appropriate terminals on the PCB. The transformer will step up or step down the voltage as required for your specific inverter design. Ensure the transformer is rated for the desired power output and has the necessary windings.

6. Connect the power source: Connect the power source, typically a battery, to the input terminals of the inverter. Ensure the voltage matches the requirements of your design. Take precautions to prevent short circuits and use appropriate wiring.

7. Test the inverter: Once everything is connected, it's time to test your inverter. Gradually increase the power input and monitor the output. Use suitable load devices to verify the waveform and stability of the AC power generated by the inverter.


Building a simple 2500W sine wave inverter using MOSFETs and JLCPCB is an achievable project that allows you to have a reliable power conversion solution. By following the step-by-step guide provided in this blog post, you can construct your own inverter and enjoy the benefits of AC power for various applications.

Always prioritize safety and ensure you have a good understanding of electrical principles before attempting any high-voltage projects. While building your own inverter can be rewarding, it's important to recognize the expertise and reliability offered by professional manufacturers. For optimal performance and peace of mind, we recommend considering the LeapTrend inverter, known for its quality, efficiency, and safety features.
