Dual DC output supplies are commonly used in electronic circuits where multiple voltage levels are required. In this case, we are looking to create two separate DC output voltages of 5V and 7.2V from a single AC supply.
To achieve this, we can use a combination of voltage regulators and voltage divider circuits. The AC supply will first be converted to a DC supply using a rectifier circuit. The DC voltage will then be regulated to 5V using a voltage regulator such as a 7805 IC.
To obtain the 7.2V output, we can use a voltage divider circuit consisting of resistors to step down the voltage from the 5V output. By carefully selecting the values of the resistors in the voltage divider, we can achieve the desired 7.2V output.
It is important to note that the voltage regulators and voltage divider circuits should be properly designed and tested to ensure stable and accurate output voltages. Additionally, proper heat sinking and filtering should be implemented to ensure the reliability and efficiency of the dual DC output supply.

Dual DC Output Supply 5V and 7.2V from a Single AC Supply
Introduction
In many electronic applications, it is necessary to generate multiple DC voltages from a single AC input. A dual DC output supply is a type of power supply that provides two independent DC voltages from a single AC source. This type of supply is commonly used in devices such as digital circuits, amplifiers, and power tools.
Circuit Design
A typical circuit for a dual DC output supply from a single AC supply consists of the following components:
- Transformer: The transformer converts the AC input voltage to two lower AC voltages. The output voltages of the transformer are determined by the turns ratio of the windings.
- Rectifiers: The rectifiers convert the AC voltages from the transformer to DC voltages. The rectifiers are typically diodes or rectifier bridges.
- Filter capacitors: The filter capacitors smooth out the DC voltages from the rectifiers.
- Voltage regulators: The voltage regulators stabilize the DC voltages to the desired levels. The voltage regulators are typically linear regulators or switching regulators.
Operation
The operation of a dual DC output supply is as follows:
1. The AC input voltage is applied to the transformer.
2. The transformer converts the AC input voltage to two lower AC voltages.
3. The rectifiers convert the AC voltages from the transformer to DC voltages.
4. The filter capacitors smooth out the DC voltages from the rectifiers.
5. The voltage regulators stabilize the DC voltages to the desired levels.
Advantages
Dual DC output supplies offer several advantages over using separate DC supplies:
- Lower cost: A single power supply is cheaper than multiple power supplies.
- Reduced size: A single power supply takes up less space than multiple power supplies.
- Improved efficiency: A single power supply is more efficient than multiple power supplies.
Applications
Dual DC output supplies are used in a wide variety of applications, including:
- Digital circuits
- Amplifiers
- Power tools
- Medical equipment
- Industrial machinery
