What is a dual power supply from a single battery?

The power supply can be single or dual. A single supply creates only one voltage, but a dual supply produces two voltages, one positive and one negative. This article focuses on the dual power supply in particular. So we have decided that in this tutorial, we are going to make a “Dual Power supply from a single battery”.

How do I create a dual power supply from two 9V batteries?

For information the power supplies have +V, -V and GND terminals. Here is how you can create a dual power supply from two 9V batteries. You can use the same principle with bench power supplies as long as the outputs are "floating". Another option would be to use switching regulators to generate the required voltages from a 12V supply.

Can a dual power supply be used as a cell phone charging circuit?

In DIY, we can use a dual power supply as a cell phone charging circuit, power bank circuit, battery-less power circuit, and also in case of any direct current power supply. A dual power supply is a regular direct current power supply, it can provide a positive as well as a negative voltage.

How to design a dual power supply circuit?

Here we design a dual power supply circuit by using a step-down transformer and linear voltage regulators. Mostly we see electronic circuits and applications operate in the DC voltage range that falls in 5, 12, and 15 Volts, therefore we are going to make three types of dual power supply circuits.

Why do we need a dual power supply?

It also ensures a stable power supply to the device as well as helps to prevent system damage. As there are some particular applications where we need both a positive and a negative voltage of the same magnitude at the same time that is where the dual power supply is a convenient option.

Why do op-amps need a bipolar output voltage?

For example, op-amps generally need to swing bipolar output voltages, and when we want to run two different power circuits on the same power supply without taking it offline It helps the device to function properly and secure from damage to the assembled equipment.
