How it Works

The circuit works by using the 2N3055 transistors as switches to convert the 12V DC power to AC power. The transistors are driven by a square wave signal generated by the 10kΩ and 1kΩ resistors. The 220uF and 10uF electrolytic capacitors filter the output voltage to ensure a stable AC waveform. The transformer steps up the output voltage to 220V AC.

Tips and Precautions

  • Use a suitable heat sink for the 2N3055 transistors to prevent overheating.
  • Ensure proper insulation and wiring to prevent electrical shock.
  • Use a fuse or circuit breaker to protect the circuit from overcurrent.
  • This is a basic circuit diagram, and you may need to add additional components or modifications to ensure safety and reliability.

Conclusion

This simple 12V to 220V inverter circuit diagram is a great starting point for beginners. With the right components and precautions, you can build a functional inverter to power small appliances or devices. Remember to always follow safety guidelines and take necessary precautions when working with electrical circuits.
