 How To Make Amazing Inverter At Home

Hi, there are friends today we will make an inverter at home with Mosfet transistor and a special oscillator board.

A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).

A typical power inverter device or circuit requires a relatively stable DC power source

capable of supplying enough current for the intended power demands of the system.

  The input voltage depends on the design and purpose of the inverter. Examples include:

12 V DC, for smaller consumer and commercial inverters that typically run from a rechargeable 12 V lead acid battery or automotive electrical outlet.24, 36 and 48 V DC, which are common standards for home energy systems.200 to 400 V DC, when power is from photovoltaic solar panels.300 to 450 V DC, when power is from electric vehicle battery packs in vehicle-to-grid systems.Hundreds of thousands of volts, where the inverter is part of a high-voltage direct current power transmission system .

The main advantage of a MOSFET is that it requires almost no input

current to control the load current, when compared with bipolar transistors. In an “enhancement mode” MOSFET, voltage applied to the gate terminal increases the conductivity of the device. In "depletion mode" transistors, voltage applied at the gate reduces the conductivity.

An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices.

With that being said let's proceed to assemble the homemade inverter.

In order to make this homemade inverter 12v to 220v we will need the following parts:

The oscillator board

The mosfet transistor: IRFZ44N

An electrical transformer no center tap(from old radio, car charger)

And a dc power supply(battery, battery pack from 18650, car auto battery)

This is the most important part of the inverter, in a proper inverter, this is replaced with an syn wave oscillator.

This board it has 3 pins: VCC.GND.Out As you see in the picture above we have to supply power separately to this board, and i just need 4v to make it run.So the + terminal from the battery goes to vccand the - terminal to GND, and out output will be the + and a common ground(-). Now the out(+) terminal we will connect to the G terminal of the mosfet (the one on the left side) and GND to the right terminal of mosfet(S).

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage

in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described this effect.

In our case, we will use the transformer in reverse, meaning we will supply power to its normal output and we will gain voltage 220v (or close) to its normal input terminals, just look for thick wires that will be the normal output(in this case our input).We will connect the input terminals between the + of the power supply and the D (middle pin of mosfet)

Now if all the connection are made and exactly to the description we should hear a humming noise and that's the

a sign that our mosfet is working beeing switch by the oscillator board and is stepping up the voltage from 12v to 220v with the help of transformer.
