220V AC to 110V AC Converter Circuit Diagram Using Transformer and Basic Components

220v ac to 110v ac converter circuit diagram

Use a step-down transformer rated for mains input and roughly half the output amplitude. A laminated core unit with a primary winding designed for European household supply and a secondary delivering about 115-volt alternating output provides stable reduction without complex electronics. Select a model with a power margin of at least 30–40 % above the load demand; for example, a device drawing 150 W should be paired with a transformer rated near 200–220 VA to prevent overheating during continuous operation.
