100W to 1000W Power Inverter Base on Transistors

If you are the type asking “can this circuit work?” the answer is YES! That is; if you make use of the components in this circuit or their equivalents and follow the connections as it is in this circuit. The Circuit was built, constructed, and tested.

Components for this Project
  1. Bipolar Junction Transistor (BJT)
  • 6822A (2)
  1. Field Effect Transistor (FET)
  • IRF3205 (4)
  1. Resistor
  • 100KΩ (2)
  • 15KΩ (2)
  • 10KΩ (2)
  1. Non Polarized Capacitor
  • 104 (3)
  • 474J, 400V (1)
  1. Center Tapped Transformer
  • 12V – 0V – 12V, 10A

The circuit is a simple DC – AC power inverter that can output 100W to 1000W using 10V to 12V battery and centre tapped transformer (12V-0V-12V, 10A).

The two NPN bipolar junction transistors (BJTs) are configured as astable multivibrator or oscillator, each with half cycle out of phase at frequencies between 50Hz to 60Hz. The four (two for each half cycles) power MOSFETs (IRF3205) amplifies each half of the AC voltage generated by the oscillator. After this, is thence fed to the power transformer which then steps up the voltage from 12V to 230V. However, one can increase the output power to up to 2500W or more by adding more power MOSFETs in parallel, greater power transformer, and larger battery power bank.

Below is the 100W to 1000W power inverter circuit diagram

The circuit below is the circuit of the power inverter that can output power ranging from 100W to up to 150W, the timer 555 is in astable multivibrator configuration. The integrated circuit (IC) 4013 divides  the oscillating output that is; it splits or divides the frequency into two separate half cycle out of phase. The power MOSFETs IRF3205 amplify the oscillating output from the IC 4013 and the transformer steps up this voltage to 110V to 230V. The frequency of the vibration is determined by the level in which the pot or variable resistor is set. The frequency can be set from 50Hz to 60Hz. The input voltages range from 10V to 12V. Furthermore, you can increase the output power of this inverter to up to 1000W or more by adding more power MOSFETs in parallel and using powerful transformer and high capacity battery power bank.

      1. Interesting, yes. Don’t stop yet, though.

        OK, now shape the inverter waveform and output into as “pure or quality” of a true sine-wave as one prudently can, and it might become more efficient and able to power more needs.

  1. can u tell me the basic concept to check or to make a circuits. I want or know that input goes which which part how is it work. my whtsapp no. is +919811448910
