Dual Power Supply Circuit Diagram With Explanation Pdf

A dual power supply is a circuit that provides two separate sources of power to a device. This can be useful for devices that require different voltages or currents, or for devices that need to be powered on even when the main power source is turned off.

Dual power supplies are typically used in electronic devices such as computers, audio equipment, and video game consoles. They can also be found in industrial equipment and medical devices.

There are two main types of dual power supplies:

*

Unregulated dual power supplies:

These power supplies provide two unregulated voltages, which means that the output voltage can vary depending on the load. Unregulated dual power supplies are typically less expensive than regulated dual power supplies, but they are also less reliable.

*

Regulated dual power supplies:

These power supplies provide two regulated voltages, which means that the output voltage is always the same, regardless of the load. Regulated dual power supplies are more expensive than unregulated dual power supplies, but they are also more reliable.

The following diagram shows a basic circuit for a dual power supply:

Dual power supply circuit diagram

The circuit consists of two voltage regulators, each of which provides a regulated output voltage. The two voltage regulators are connected to a common transformer, which provides the input voltage to the circuit.

The following table lists the components used in the circuit:

| Component | Description | |---|---| | Transformer | Provides the input voltage to the circuit | | Voltage Regulator 1 | Provides a regulated output voltage of +5 V | | Voltage Regulator 2 | Provides a regulated output voltage of -5 V | | Capacitor | Filters the output voltage of the voltage regulators | | Diode | Protects the voltage regulators from reverse polarity |

Dual power supplies are an important part of many electronic devices. They provide the necessary power to operate the device and ensure that the device is protected from damage.
