As we know that inverter is a circuit that converts the direct current into an alternating current. And, therefore widely used in electronic circuitry. From small gadgets to complex electronic devices, inverters are used often. Thus, we cannot disavow that for small electronic projects, it’s sometimes difficult to convert the direct power into an alternating current power. So, in this article, we are trying to make a simple inverter that helps beginners to understand the process. The circuit is easy to make and can easily be utilized in electronic devices.
For making a circuit, the transformer is used as the primary component. Hence, you can use the transformer from your old mobile phone charger. But, remember, not all mobile phone transformers are the same. Therefore, must check the transformer before wiring it into the circuit of the inverter.

4V to 220V Inverter Circuit
Working Explanation
When you connect the circuit according to the diagram given above and applied the DC power to it, the transistor 13005 does the high-speed switching. The base of this transistor controls the biasing, and the emitter that is connected to the ground drains out the current. Hence, the current flows through the collector which is connected to the transformer wired to step up the voltage. As a result, the transformer in the circuit drives the load of this simple inverter.
Applications
- Above all, lightning systems can utilize this circuit.
- Also, It can also be utilized in the indicator circuits that use AC power.
- Further, for any AC circuits that include low DC voltage to convert.
- In other words, kitchen appliances, televisions, mixers, power tools, conveyors, etc are some simple applications of inverter circuits.
