Explanation of common problems and maintenance methods of switching power supply

What is the working principle of switching power supply 12V?The output power of the switching power supply of 12V is generally 6W, so when the input ac voltage varies in the range of 110 to 260V, the voltage adjustment rate Sv≤1%, when the load current varies greatly, the load adjustment rate SI=5% ~ 7%, is to simplify the circuit, here the basic feedback mode.

TITLE:What is the difference between a switching power supply and a linear power supply；Linear power supply and switching power supply have their unique features in different scenarios. For example, linear power supply can be used in very demanding situations, because the output of linear power supply is direct current.

Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

What are the modes of operation of switching power supply?Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

For switching power supply, the working principle of switching transformer is different from that of ordinary transformer. The normal transformer input ac voltage or current of the positive, negative half cycle waveform are symmetrical, and the input voltage and current waveform are generally continuous, in a period, the average value of the input voltage and current is equal to 0, this is the basic characteristics of the ordinary transformer working principle;

What are the benefits of increasing the frequency of SMPS switches?Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

How should the failure appear in the process that USES switch power supply solve?Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

Why switch power supply? Instead of linear power?Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

Why is switching power more popular?Kulon electronics is the global distributor of MeanWell switching power supplies, providing all MeanWell switching power products and models.

Switching power Adapter Pattern is the transformation of the interface of a class into another interface representation that the client expects, primarily for compatibility, so that two classes that would otherwise not work together because of interface mismatches can work together. It is alias Wrapper and is a structural pattern.

Switching power adapter the connection between the computer and the external LAN is made using a communication adapter.An adapter is originally a network interface board (or a PCMCIA card) that is plugged into the host computer. This type of interface board is called network interface card.

What can a switching power adapter be used for?Switch power adapters have a name, called external power supply. Is a relatively small portable electronic equipment and electrical and electronic supply transformer. It is because in the use of electronic devices are often not directly use power, easy to cause electrical short circuit, so the role of the switch power adapter is to help us safely use our electronic products.
