Powerful inverter (3 to 220v) Using an old adapter

Components:
3.7 v adaptor
D882 transistor
33 ohm Resistor

Important Note:
Always insert the bulb into the screw head before connecting the battery to the circuit. Failing to do so can lead to excessive current flow, potentially damaging the components or causing the circuit to burn out.

Description:
This project demonstrates a simple yet effective design for converting a low 3.7V DC input into a high 220V AC output using a transformer, a transistor (D882), and a resistor. The circuit is compact and cost-effective, making it suitable for low-power applications and educational purposes.
The transformer is the core component responsible for stepping up the voltage. It operates based on the principle of electromagnetic induction, where a changing current in the primary winding generates a proportional magnetic field, inducing a higher voltage in the secondary winding.
