So you want to know what is an AC adapter, right? It’s great. You know, sharing a piece of knowledge seems fantastic when you people show your thirst. After all, it’s an interactive process.
Anyway, here in this post, we will provide you with a robust notion of AC adapters. You will learn its definition, advantages, disadvantages, how to use it, and so on!
Definition of AC Power Adapter
An AC power adapter is also familiar as AC/DC adapter, AC converter, or charger. For electronic devices, it supplies power. Such an external power supply runs on batteries. Electronic devices get this so that they don’t need to rely on other power sources. Getting plugged into a wall outlet power adapters convert AC to a single DC voltage.
You can merely use it with the devices that match its requirements. The reason is, the power rating and types of the plug are not universal. Every AC adapter has a specific power rating of its own. Experts measure this in volts or watts.
You can also employ your power adapter to output a ”different” AC voltage instead of DC. For example as –
- power supply
- power distribution unit
- wall wart
- wall tap, power strip, and USB charger
An AC power adapter features a transformer. It converts the power grid voltage to a lower voltage that is known as a rectifier. By origin, most AC/DC adapters were linear power supplies. The transformer determines the size and weight of the device significantly.
A designed linear cut needs a transformer apt for the frequency. Generally, the frequency is 50 or 60 Hz. However, a switched-mode supply can function efficiently under overvoltages of various ranges and frequencies. You can take care of any power grid with a 100–240 VAC unit.
Why Ac Power Adapter Is Necessary for laptops?
And as we mentioned above, it becomes quite handy for laptops in the same way. Most importantly, these AC converters or adapters deaden the need for a standard-sized power supply. Thus, they reduce the size of laptops.
Merits of AC Power Adapter
Our portable electronic devices are immensely dependent on AC power adapters. There are a number of advantages of such an adapter. Would you mind getting them one by one? Here they are!
Increased Reliability and Longevity
Heat is the culprit that hampers the durability of electronic devices. At the same time, it makes sensitive circuits malfunction. Here an external adapter becomes your savior. It significantly reduces heat from your device and keeps it safe.
You can use all the externally powered electronic devices along with different power sources. No matter if it is 12 VDC, 120 VAC, 240 VAC, or any external battery pack.
The innovation and development of AC adapters relaxed the product designers. They are no longer afraid of losing their design quality. They don’t have to face any insecure voltages inside the enclosure.
Burdened off Portability
Your external adapter removes the burden of weighty power components. Apart from that, it reduces their size making them comfortably portable.
You can enjoy voltage constantly with the help of a specific type of adapter. These are known as eliminators, and ease the usage of laptops and computers.
You don’t need to repair your powered devices in the case of any power failure. The external adapter you employ will take care of them.
Demerits of AC Power Adapters
Let’s talk about some disadvantages as well. This is not telling merely for the sake of description. Instead, it is a fact. And the fact is, still, the external adapters lack standardization. A number of customers are dissatisfied with the high price, inconvenience, and longevity issues.
Frequently Asked Question
Ac Power Adapters- How Useful to Computers
Computers use multiple DC voltages. That means they are in need of an adapter since it externally works as their power supply. Internal circuits create additional DC voltages. The power supplies of a desktop computer lie in one internal unit. This unit turns AC into all DC voltages.
Now you fully know what is an AC power adapter. The fact is, it has been a part of our daily life. Whenever we go, it accompanies us. Despite having some demerits, it benefits us to a large extent.
Have a good day!
