Make your own 12V to 220V Inverter
We have previously published several articles about inverters, but they were only theoretical explanations and were rarely put into practice. One of the important reasons is the lack of documentation, but we also want to test the feasibility of the circuit for everyone and successfully implement it ourselves. That feeling is incomparable, no matter how many finished products we buy. Our production topic this time is still how to make it simple. The article will also share the test results with everyone.

| Circuit diagram of simple inverter |
The picture above is the diagram of our inverter. This time, we use a larger power transistor, 2N3055, and only two resistors. It is best to choose a larger resistor capacity so that the output power of the circuit increases correspondingly. The picture above uses a 1W 400 ohm resistor. If there is no 1W resistor, it's okay. The most commonly used resistor is the 1/4W resistor. Just choose four resistors in parallel to get about 400Ω.

The picture above shows two components that are not easily seen. The first picture is a transformer with a shaft end. The capacity of the transformer used here is 10W. The capacity is small, and it can be difficult to control any load once you do. You can use an LED light to check.

Many of you want to know how it works. This is essentially an oscillator circuit, converting DC power to AC power, then increasing it to 220V through a transformer, and then connecting electrical devices to the output. Some of these ingredients. Inverter, the output waveform is definitely not grid standard, but it is enough to control the light bulb.

This is a 12V power source with an output capacity of up to 65W. If you have solar panels or a stronger power source at home, you can use it directly. However, please note that the voltage must be 12V. Once you find these components, you can connect the circuit.
Actual connection to the inverter
The picture above is the actual connection circuit diagram. You can see the resistor consists of four 1/4W resistors connected in parallel. However, due to the low capacity of this transformer, the parallel connection of these four components is also overkill. According to the diagram, make the electrical connection and power on after the last check is correct, but remember to note that the output voltage has exceeded the safe voltage for humans and the following actions must be taken: Safety measures during operation.

Check circuit feasibility
The editor here uses a multimeter to demonstrate the test because there is no suitable electrical equipment, and the power source of the transformer is weak and cannot control large-capacity electrical equipment, so a multimeter is used instead of electrical equipment to check output voltage. Adjust the multimeter to the appropriate settings, do all the work, turn on the power, and observe the multimeter readings.

| Successfully tested with a voltage (with AC) of 211 V. Need to increase the input voltage a bit to get 220V. |
After turning on the power, you can hear the signal fluctuation sound. At this time, you can read the voltage indicator on our multimeter as 211V and very stable.
Here's what's needed and cheap for a device that generates electricity for another home:
🔹 Version from Nikola Tesla's "Magnifying Transmitter"
🔹 The "tension" for "electricity fractionation" to occur is the Earth's Potential Potential. To be precise, it is the tension of the Ether, and the electricity is the dynamic polarization of the Ether.
🔹 During "Electricity segment", the magnetic field collapses several times in short periods of time. That leads the voltage V = Φ/t to reach infinity (V → ∞) when t → 0
- V - The electromotive force which results from the production or consumption of the total magnetic induction Φ (Phi). The unit is the “Volt”. Where t is the time of magnetic field collapse from maximum to complete collapse.
- Research scholars also call it Tesla's technology called Radiant Energy from Electronic Circuits, Impulse Technology.
