how to make 5v 9v 12v power supply How to Make a 5V, 9V, and 12V Power Supply

A multi-output power supply is useful for powering various electronic devices. Here’s how to build a power supply that provides 5V, 9V, and 12V outputs.

Materials Required:

230V to 15V Transformer

Bridge Rectifier (1N4007 x 4)

Capacitors (1000µF, 470µF, 10µF)

Voltage Regulators (7805 for 5V, 7809 for 9V, 7812 for 12V)

Heat Sinks for Regulators

Diodes (1N4007)

PCB or Perfboard

Wires and Connectors

Circuit Description:

1. AC to DC Conversion:

Use a 230V to 15V step-down transformer to lower the voltage.

Convert AC to DC using a bridge rectifier (four 1N4007 diodes).

Smooth the rectified voltage using a 1000µF capacitor.

2. Voltage Regulation:

The rectified DC voltage (about 15V) is fed into three voltage regulators:

7812 for 12V output

7809 for 9V output

7805 for 5V output

Each regulator needs a heat sink to prevent overheating.

3. Output Filtering:

Use capacitors (10µF and 470µF) at each regulator's output to stabilize the voltage.

Add diodes (1N4007) at each output to protect against reverse voltage.

4. Final Connections:

Connect the regulated outputs to terminal blocks for easy access.

Ensure proper insulation and testing with a multimeter before using.
