Customer Reviews
"We appreciate so much of your excellent work on this new project,we are very impressed by your flexible ability from the designing to the production ."

—— Colin.Angle

We tested samples and found they are all good and the price is fine. I appreciate all of the assistance,it is very happy to work with you.We have another device also need power adapters, you will receive more order from us.

—— Jim.Krzeminski

Actually,our cooperation started from many years ago, I still remmber that our first meet in Hong Kong fair with Lily and Lotus,and after that my techinical engineer and I visited your factory in Dongguan. Your factory and products are very impressive. We look forward to prosperous relationship with Analog Power Electronic in 2022 and beyond.

—— Scott.Ledterman

I look forward for my many orders to come.It's not so much about money or how much time it cost . It's about the flexibility and professionalism too.Analog is always reliable and it's great to be our partners for several years.

—— Garrett.Breheny

Analog Power Electronic makes awesome switching power supply and battery charges for our household smart appliance products which has always supported us in our product reliability, quality, compatibility and safety. We are very pleased to work with them.

—— Kaitlin.Bonner

It's really a good partner for us who we could place our trust in till now from China. They are specilist in power supply and switching power adapters.On this important dimension, we have to say that the we now has much more significant to work with Analog Power Electronic than ever before.

How many types of power supply technology you know?


There are 2 types of power supply technology:Linear power supply and Switching power supply
 

1.Linear power supply

 

This type of power supply provides one or more stabilized and constant DC voltages despite the fluctuations of the network.

This system often consists of a transformer, a rectifier, a filter and a regulator.

 

The transformer reduces the amplitude of the power grid voltage, the rectifier converts the AC voltage into a DC voltage, the filter stores the energy in order to smooth the output voltage of the rectifier while the regulator stabilizes and regulates the output voltage.

Linear power supply can deliver from a few watts up to several hundred watts.

 

Applications: this type of power supply is suitable for audio equipment and laboratory power supplies.


Advantages: this type of power supply is easy to set up, offers good stability and allows good temperature resistance.


Disadvantages: this type of power supply offers poor performance and generates energy losses. Linear power supply is also heavy due to its voluminous structure.

 

2.Switching power supply

 

With this type of power supply, the electrical regulation is ensured by power electronic components such as transistors, used in switching. Unlike linear power supply, switching power supply allows instantaneous power transmission.

 

Switching power supplies have been developed since the 1980s to overcome the drawbacks of linear power supplies (high weight and low efficiency).

 

Applications: this type of power supply is suitable for “consumer” electronic devices such as computers, televisions, phone chargers, etc.


Advantages: this type of power supply has very good performance. Because the size of the transformer is small, the weight and volume of the entire system are reduced.


Disadvantages: this type of power supply generates harmonic noise and residual waves remain.
