For many engineers who are developing switching power adapter products , sending new products to relevant departments and conducting strict CE certification is the most critical part of the entire R&D process, and it is directly related to whether the products can meet export standards. . So, what exactly is this CE certification? What are the requirements for CE certification for switching power adapters? Let's take a look at it below.   In fact, this so-called CE certification is an abbreviation for the certification of products in the EU countries. If the new product of the switching power adapter wants to be exported to a European country, then it must carry the "CE" mark, which is also a pass order for entering European countries. This symbol indicates that the product complies with one or several relevant European directives. This is enforced by law. During the certification audit process, the power adapter products will be inspected for production quality, pr...

The mobile phone charger uses high-frequency power technology and uses advanced intelligent dynamic adjustment charging technology. The power frequency machine is designed based on the traditional analog circuit principle. The internal power components of the machine (such as transformers, inductors, capacitors, etc.) are relatively large. Generally, there is less noise when the load is larger, but the model is bad. The power grid environmental conditions have strong resistance, and the reliability and stability are stronger than those of high frequency machines. The charger is divided according to the operating frequency of the designed circuit, and can be divided into a power frequency machine and a high frequency machine. The power frequency machine is designed based on the traditional analog circuit principle. The internal power components (such as transformers, inductors, capacitors, etc.) of the machine are large. Generally, there is less noise when the load is running at a la...
