# What is DC dual power supply?

## What is DC dual power supply?

A Dual power supply is a regular direct current power supply. It can provide a positive as well as negative voltage. It ensures stable power supply to the device as well as it helps to prevent system damage. Many electronic circuits require a source of DC power.

### Can you connect 2 DC power supplies in series?

The outputs of two or more power supplies can also be connected in series if the object is to obtain a higher current at the required voltage, since lower voltage supplies usually have higher current ratings. The power supplies could have different voltages allowing greater flexibility of the final output voltage.

#### Which IC is used to obtain 15V regulated DC voltage?

Voltage Regulation For providing a regulated 0V to 15V, LM317 IC is used. The voltage regulator IC is capable of providing a current of 1.5A, so is well suited for the current requirement of 1A. In this circuit, LM317 will provide an adjustable voltage corresponding to its input voltage.

What is 15V battery?

What is a 1.5v Battery? A classic nominal voltage, most AA, AAA, C, & D cells are 1.5 volts, and many household and handheld devices have been built to use that voltage. The first zinc-carbon dry cells naturally produced 1.5 volts of energy, and has remained the standard ever since.

How do you split DC power supply?

use three pin regulator for the positive voltage and use DC polarity inverter IC to get negative voltage and then use three pin regulator (79XX) for negative voltage. Simple resistor divider can split voltage in to number of voltages. If you use two same resistor, it will split voltage in to half.

## What are various techniques to make dual power supply?

Constructing Dual Power Supply Circuit:

• Step-I: Converting 220v AC into 12v AC using Step Down Transformer.
• INPUT: 220V ac, 50 Hz.
• OUTPUT: Between outer terminal and middle terminal: 12V ac, 50 Hz.
• Step – II: Converting 12v AC into 12v DC using Full Bridge Rectifier.
• Here, full bridge rectifier is used.
• INPUT: 12V ac.

### How do I connect two DC power supplies?

Two or more power supplies can be connected to supply higher voltages or current. The simplest method to create higher voltage is to connect the power supplies in series, set each supply to output the same voltage and each supply should have the same current limit.

#### What happens if you connect two power supplies together?

A common topology employed to increase output power is to connect the outputs of two or more supplies in parallel. In this configuration each power supply delivers the required load voltage while connecting the supplies in parallel increases the available load current and thus the available load power.
