Continuously Variable DC Dual Power Supply

About Continuously Variable DC Dual Power Supply

A Regulated Power Supply is an electronic device that provides a constant output voltage (or current) regardless of changes in input voltage or load conditions. It is widely used to power electronic circuits and devices that require stable and precise voltage levels

It converts an unregulated AC (from the mains) to a stable DC output. It ensures that even if the input fluctuates or the load changes, the output remains steady

• Transformer

  • Steps up or steps down the input AC voltage.

• Rectifier

  • Converts AC to pulsating DC.

  • Common types: Half-wave, Full-wave, and Bridge rectifiers.

• Filter

  • Smooths out the pulsating DC.

  • Usually made of capacitors and sometimes inductors.

• Voltage Regulator

  • Maintains a constant output voltage.

  • Types:

    • Linear Regulators (e.g., 7805 for +5V)

    • Switching Regulators (more efficient)

    • Zener Diode based (simple, for low-power applications)
