Push-Pull Inverter 12V to 220V
This circuit is specifically designed to convert 12V DC into 220V DC, making it suitable for powering devices with AC input that internally use a bridge rectifier, such as power
In conclusion, an inverter circuit diagram for converting 12V DC power to 220V AC power typically involves a DC power source, an oscillator, a transformer, and switching components. This circuit allows you to power AC devices using a low voltage DC power source, making it useful in a variety of applications where AC power is needed.
That high voltage comes out as back EMF and reaches the output side. This high voltage can reach around 220V or whatever coil is designed for. And that is how we get our AC like 220V output at the terminal. This full ON OFF action happens very fast at the oscillator frequency and that makes a continuous 220V supply at the output terminal.
This part is added so that we do not allow the voltage to cross 220V. So you can adjust the 47k preset to fix the voltage level. Even if the coil gives more back EMF or the battery voltage changes a bit then still the output will not go above 220V because of this BC547 feedback.
Connect pin 8 to +12V supply line Connect pin 1 to ground Now connect 4k7 resistor from pin 8 to pin 7 Then connect 1k resistor from pin 7 to pin 6 Put 680pF capacitor from pin 6 to ground Short pin 6 and pin 2 Connect a 10nF (marked as 103) capacitor from pin 5 to ground Connect pin 4 directly to +12V
