Power Supply</a> is designed for high efficiency and small size. They incorporate a
switching regulator to convert electrical power efficiently. Switching DC power supplies
regulate the output voltage through a process called pulse width modulation (PWM). Using a
PWM allows various topologies to be used such as buck, boost, forward converter, half-
bridge rectifier, or flyback depending on the output power requirements. The PWM process
generates some high-frequency noise but enables the switching power supplies to be built
with very high power efficiency and a small form factor. With a good design, a switching
power supply can have excellent load and line regulation. They can either step up or step
down the input voltage to get the desired output voltage. A switching power supply has
greater efficiency than linear regulators because the switching transistor dissipates
little power when acting as a switch. However, this switching can generate noise which can
be lowered by filtering.

If your equipment is for international use, switching technology works almost anywhere
in the world whereas a linear power supply must be manually adjusted to work with a
foreign grid. Other examples of applications that prefer a switching <a

Frame Power Supply</a> are general purpose ones used in R&D, manufacturing, and
testing, high power / high current applications, some communication systems, mobile
stations, some network equipment, electroplating, anodizing, electroforming,
electrophoresis, electrolysis, waste treatment, hydrogen generator, fuel cell
applications, DC motors, aviation, and shipboard/boat applications.

<strong>What is an AC Adapter?</strong>
</p>

<div>
<p>
<a id="primer"></a>An AC <a href="https://www.etopsmps.com/power-
adapter/">Power Adapter</a> is an external power supply that converts alternating current
(AC) from a wall outlet to a direct current (DC) needed by an electronic device.
Therefore, it is an AC/DC converter. When it supplies power to a battery-powered device,
it is also accurate to describe it as a charger. Before picking the right AC adapter for
your device, it is useful to know the reasons most portable electronics use external power
adapters.
</p>
<p>
Installing the power components of devices in external AC adapters allows
manufacturers to make them smaller. Those researching how to choose the right AC adapter
should know that devices with external power adapters are lighter than those with
integrated AC adapters. Having a separate and external AC/DC power adapter also reduces
the heat produced inside an electronic device. This design also reduces electrical noise
and improves safety.
</p>
<p>
A manufacturer can also support a wide voltage range by choosing an external
power supply when designing the right AC adapter for your device. Lastly, external power
adapters are easier to replace. Users do not have to throw away their devices if voltage
spikes, or in the case of brownouts or electrical fires destroy their external power
supply units.

<strong>Check Electrical Ratings to Choose the Right AC Adapter for Your
Device</strong>
</p>
<p>
Before trying to find a matching AC <a href="https://www.etopsmps.com/power-
adapter/desktop-power-adaptor/">Desktop Power Adaptor</a> for a device, check if the OEM
(original equipment manufacturer) adapter is available. Device manufacturers sometimes
offer replacement chargers/adapters for their products. Determining how to choose the
right power adapter for a device becomes easy if this OEM accessory is available. Find the
specific adapter for the device by searching for it using the model number printed on the
adapter shipped with the device.
</p>

<p>
In some cases, OEM adapters are no longer available from manufacturers. Therefore,
finding the right AC adapter for your electronics requires selecting a compatible third-
party accessory. The first step is to determine the electrical rating of the
device.<br/>When learning how to choose an AC adapter, it is also necessary to understand
power adapter specifications. Manufacturers usually print such information on the labels
of these power accessories. Alternatively, check the device’s user manual for the
electrical ratings of its AC adapter. The most important sections to read on a power
adapter label are voltage and current. However, polarity is also an important factor.

Remember the times when our smartphones required an entire night for a complete
recharge? We are pretty sure there were also many instances here you left home with little
charge on your phone and you might have regretted it. The introduction of fast <a
href="https://www.etopsmps.com/fast-charger/car-charger/">Car Charger</a> technology has
changed it all. Just plug in your phone for a few minutes and your device has enough juice
to keep running the entire day.
</p>
<p>
Fast charging tech is a boon for smartphone users and it helps users to live their
lives in the fast lane. Have you ever wondered how fast charging works? Dive in, to get a
better understanding towards the fast charging technology.

<p>
<strong>How does fast charging work?</strong>
</p>
<p>
The fast charging follows the same principle as the standard charging but the
electrical power (Ampere) converted and transferred via the cable is much higher than that
of a standard charger. A standard adaptor’s voltage ranges from as low as 2 volts to 4.2
volts with a relatively low electrical transfer rate. However, a fast charging adaptor is
capable of building a much higher voltage (5V-12V) with a faster electrical transfers
until the battery reaches its peak voltage capacity.
</p>
<p>
What does peak voltage capacity mean? It is the optimum capacity of a battery to
charge quickly. As the battery reaches 50 to 60 per cent (peak voltage capacity of
standard batteries), the electronic controller (IC) drops down the voltage intakes to
