POWER 3000W Inverter using Mosfet IRFZ44N x 6 // Sine Wave, DC 12v To 220v AC

Making a 3000W inverter with the parts recorded includes making a DC-to-AC inverter circuit, basically involving the CD4047BE IC for creating the expected swaying and MOSFETs like the IRFZ44N for exchanging. Here is a step-by-step guide :

 

Components Needed:

1. CD4047BE IC: Astable/monostable multivibrator to create the expected recurrence.

2. IRFZ44N MOSFETs x 6: High-power MOSFETs for exchanging ( you can add more mosfet for high watt )

3. Transformer: To move forward the voltage from 12V DC to 230V AC ( You like 12-0-12v to 230 650-1500 watt )

4. Capacitors: For sifting and settling the voltage (You like 1000uf/25v, 10uf/25v, 333j or 473j/100v )

5. Resistors: To set the recurrence and for MOSFET gate assurance (10E x 6, 3.3E x 2, 22k x 2, 5.6k x 2, 15k, 82k, 1k, 4.7k, all 1/4w).

6. Heatsinks: Utilize large heatsinks or cooling for the MOSFETs to forestall overheating.

7. Battery: 12V 32-220Ah battery (with sufficient ability to deal with 3000W).

8. TIP41: Bipolar Junction Transistor

9. Diodes IN4007 x 2

10. 12V Zener Diode

11. Switch for input supply On/Off

Steps to Build the Inverter:

Set Up the Oscillator Circuit:

Connect the CD4047BE IC in Astable Mode to produce a square wave.

Connect pins 1 and 2 to a resistor (regularly 82K) and capacitor (commonly Pf 333j) to set the wavering repetition.

Pin 10 and Pin 11 of CD4047 will give you the two adjusting square wave outputs.

Drive the MOSFETs:

Associate the results from the CD4047 (pins 10 and 11) to the gates of the IRFZ44 MOSFETs through 10E resistors. This will guarantee appropriate entryway drive and switching of the MOSFETs.

**Video Capture**

Power Stage:

> Connect a 12V battery to the input of the MOSFETs.

> Associate the source terminals of the IRFZ44 MOSFETs to the negative terminal of the battery. 

> The drain terminals of the MOSFETs will associate with the primary side of the transformer (12-0-12V).

> Ensure the middle tap of the transformer is associated with the positive terminal of the battery.

> Ensure the battery can providee adequate current. For 3000W at 12V, the ongoing necessity is 3000𝑊/12𝑉=250𝐴.

Boosting the Output Voltage:

The transformer's secondary side ( 220V side ) will create the AC voltage.

Ensure the transformer rating is sufficient to deal with the power (2000W ormore )

Protection and Regulation:

Use IN4007 diodes for flyback security across the MOSFETs. 

Carry out a 12V Zener diode for voltage guideline if necessary.

Final Assembly:

Interface a switch between the battery and the remainder of the circuit to turn the inverter on and off.

Ensure all associations are secure, and double check for any wrong wiring.

CD4047 IC Pin Configuration:

1. Pin 1 (Astable output frequency): Associated with a 10µF capacitor.

2. Pin 2 (Astable output frequency): Associated with a 82k resistor. You can interface resistor 82k + 10k pot for recurrence change .

3. Pin 10 (Output): Associated with the entryway of the principal IRFZ44 MOSFET by means of 3.3E + 10E resistor.

4. Pin 11 (Output): Associated with the entryway of the second IRFZ44 MOSFET by means of 3.3E + 10E resistor .

Transformer Connections:

Primary side: Connected to the drain of the Irfz44n mosfet.

Secondary side: Outputs the 220V AC.

MOSFET CONNECTIONS:

Output to the battery negative terminal .

Drain to transformer primary winding 12v - 12v.

Testing:

Start with a low-power load to test the circuit.

Use an oscilloscope to check the waveform at the transformer result to ensure it is a perfect sine wave.

Steadily increment the heap and screen the circuit for any overheating or shakiness .

Safety Considerations:

High voltage is hazardous; ensure all associations are protected appropriately.

Utilize proper wires and circuit breakers to safeguard against short circuits.

By following these means and cautiously gathering the parts, you ought to have the option to construct a useful 3000W inverter. Ensure appropriate cooling and intensity dispersal for the mosfetss and transformer, as they will deal with huge power.
