Therefore, the multimeter is used instead of the electrical appliance to test the output voltage. Here, the maker demonstrates the test with a multimeter because there is no suitable electrical appliance, and the power of the transformer is low, and the high-power electrical appliance cannot be driven. Electrical connection can be made after the final inspection is correct, but it must be noted that the output voltage has exceeded the human safety voltage, and safety measures should be taken during operation. However, due to the low power of this transformer, these four components are also used in parallel. You can see that the resistor is composed of four 1/4W resistors in parallel. The figure above is the actual connection circuit diagram. This is a 12V Li-ion battery, the output power can reach 65W, if you have more power solar panels or power supply in your home, you can use it directly, but pay attention to the voltage needs to be 12V, you can connect the circuit after finding these components. The output waveform must have no grid standard, but driving the bulb is sufficient. This is actually a oscillating circuit, which turns the DC power into AC power, then turns it into 220V through the transformer boost, and then connects the electrical device to the output terminal, but the inverter made by these components. Many friends want to know the working principle. After you make it, you can use the LED light to go. The power is small and can hardly drive any load. The power of the transformer used here is 10W. The first picture is a transformer with a shaft head, the second is 2N3055 power transistor. The above picture is two components that are not easy to see. Just select four resistors in parallel and it is about 400Ω. The above figure uses a 1W 400 ohm resistor. This time we used the larger power transistor 2N3055, and only two resistors are used, and the power of the resistor is selected to be larger, so the output power of the circuit will be corresponding. The picture above is our inverter schematic.
