This diagram illustrates a basic circuit for a square wave DC-to-AC power inverter. The circuit converts a 12V DC input (typically from a battery) into a 220V AC output.
Key Components and Operation:
Transformer: A center-tapped transformer (labeled 0 - 220 on the primary/AC side and 12 - 0 - 12 on the secondary/DC side) is used. In this configuration, it acts in reverse: the 12-0-12 winding receives the pulsed DC power, and the 0-220 winding outputs the high-voltage AC.
Transistors (Power Switches): Two D718 power transistors are shown. These are connected to the outer ends of the 12-0-12 winding. These transistors are alternately switched ON and OFF (by an external oscillating circuit, which is not fully shown but implied) to create a fluctuating, center-tapped DC signal that mimics AC, driving the transformer.
Resistors: Two 220 \Omega resistors are connected to the base terminals (blue wires) of the transistors. These likely form part of the base-biasing and current-limiting network for the switching circuit (such as a self-oscillating multivibrator configuration like an astable multivibrator, or a simple driven switch).
This type of inverter is commonly used for low-power applications or as an educational example of converting DC power to high-voltage AC power.AC 220V To DC 12V 3A Power Supply Circuit || How to Convert AC 220V to DC 12V 3A || 12V 3A Adapter || DC Power Supply

This is Unregulated Power Supply (A circuit diagram of regulated power supply will be given shortly.)
If you measure the DC voltage at the output of this circuit with a meter, it will show 16 to 18 volts, but if you connect a load, it will show 12 volts.
