difference between power supply and battery charger

Power supply and battery charger are two commonly used electronic devices that provide power to various devices. However, despite their similarities, they have distinct differences in terms of their functions, designs, and applications. In this article, we will explore the differences between power supply and battery charger.

 

Function

 

The main function of a power supply is to convert AC (alternating current) voltage from the mains supply into DC (direct current) voltage that can be used by electronic devices. Power supplies are commonly used in a wide range of electronic devices, including computers, TVs, and radios. They are designed to provide a stable and constant voltage output, regardless of fluctuations in the input voltage.

 

On the other hand, a battery charger is used to charge rechargeable batteries. It is designed to convert AC voltage into DC voltage, which is used to charge the battery. Battery chargers are commonly used in smartphones, laptops, and other electronic devices that use rechargeable batteries.

 

Design

 

Power supplies come in a variety of designs and sizes, depending on their intended application. They can be built into the electronic device, as is the case with many consumer electronics, or they can be standalone devices, such as those used in industrial applications. Power supplies can be linear or switching, with switching power supplies being more efficient and compact.

 

Battery chargers, on the other hand, are designed to be compact and portable. They are often built into the electronic device or come as separate devices. Battery chargers are designed to be compatible with specific batteries, and their charging process is controlled by a microprocessor.

 

Applications

 

Power supplies are used in a wide range of applications, from powering small electronic devices to entire factories. They are commonly used in computers, televisions, radios, and other consumer electronics. Power supplies are also used in industrial applications, such as in manufacturing and automation systems.

 

Battery chargers, on the other hand, are used primarily in portable electronic devices, such as smartphones, laptops, and cameras. They are designed to charge rechargeable batteries and are often built into the device itself. Battery chargers are also used in electric vehicles, such as electric cars and bicycles.

 

 

Conclusion

 

In conclusion, power supplies and battery chargers are two essential electronic devices that provide power to a wide range of electronic devices. While they share some similarities, such as converting AC voltage into DC voltage, they have distinct differences in terms of their functions, designs, and applications. Understanding the differences between power supplies and battery chargers is essential for selecting the right device for a particular application.
