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 does a dual power supply work?

Both Q1 and Q2 will conduct extra current to compensate for the difference if the currents consumed by the two loads are dissimilar. In this manner, the ground voltage is maintained exactly midway between the positive and negative rails. The complete dual power supply circuit is shown in Figure 2 using 2N3055 transistors as the driver transistor.

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.

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 many types of dual power supply circuits are there?

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. All circuits have individual step-down transformers and voltage regulators, if you want you may include an LED indicator. Circuits are listed as,

Which direction does a motor move in a dual power supply?

For example, motors which are used in toys (car, bus etc), will move forward in case of +12V and it will move reverse in case of -12V. We have shown the motor rotation in both the directions, using this Dual Power Supply circuit, in the Video below.
