Make your own 12v to 380v inverter

Double-check the connections and the code before powering up the circuit. This simple 12V DC to 230V AC inverter can be used in various DIY projects and applications, including: Backup Power Systems: Use it to power small devices during power outages. Renewable Energy: Integrate it with solar panels to convert DC energy into usable AC.

The circuit of this DIY power inverter is shown in the following figure. After the 12V DC power is connected, the multi-vibrator that is composed of V1, V2, R1-R4, C1 and C2 starts oscillation, and the collector of V1 and V2 takes turns to output about 50Hz of square wave with positive polarity.

To clearly understand how to build an inverter, let's go through the following simple construction details: As per the circuit schematic first complete the assembly of the oscillator section consisting of the smaller parts and the IC. It is best done by interconnecting the component leads itself and soldering the joints.

The aim of the inverter circuit is to convert 12VDC to 220VAC, Now to achieve this, we have to first convert 12VDC to 12VAC first followed by 12VAC to 220VAC using a step up transformer. In short, we can classify the designing of inverter circuit into three stages: 1) Driver stage 2) Power stage 3) Transformer

To build this inverter, you'll need the following components: The circuit diagram of Arduino based Inverter is shown below. The schematic for the inverter circuit involves three main stages: Arduino Output Pins: Arduino pins 9 and 10 are used to generate the SPWM signals.

The story begins with an ugly device bought from China that was supposed to be an 230V inverter. But it was only a kind of high voltage generator, at the frequency of 20KHz. Absolutely nothing to regulate the output voltage, and no 50Hz to make supposing a AC use of this high voltage.
