Inverter with three components (how to do 12v to 220v inverter)

Three components to make a high power inverter 12v to 220v

The method of sharing this inverter for everyone today is the simplest one and the lowest cost. There are a lot of methods for making inverters before. Of course, we hope that the simpler the better, the fewer components we use, the lower the cost, the better, the better we can understand.

As the name suggests, the inverter is the reverse working state of the normal transformer. The most we use is to convert 220v to 12v, and rarely convert from 12v to 220v, because the source of electricity we use is mainly from the grid, so we The electricity used is from the grid, and the electricity we use is rarely converted into electricity. What do we mean by doing this inverter? You can understand this, one is the enthusiasm of electronic enthusiasts, they like to make by nature, and we are ready to use urgently. For example, if the grid stops supplying power, we can use inverter to convert it into 220v, so it will not affect our home. Normal power supply, and with the popularity of solar panels, we may one day be exposed to the grid voltage that converts solar power into 220v.

Let's take a look at the schematic of our inverter.

How is the schematic diagram simple? This is also the circuit that diy often touches. Through the circuit diagram, we can see that the components used have three resistors, and there are two triodes, and one transformer is left. Let me tell you one by one. Each component.

resistance

First of all, the next three resistors, the two resistors connected to the two transistors and the transformer, do not choose too large, usually a few ohms, want to do the inverter with large output power, then the resistor chooses the small point If there is not such a small resistance, it can be wound with a resistance wire. The other resistor is usually around 300 ohms. This resistor is used to prevent the circuit from vibrating. When the load is different, the resistor may be slightly different. We can use a sliding rheostat to adjust it in real time.
