Low frequency transformers, as an important electrical equipment, are widely used in fields such as communication, electronics, and power. This article will provide a detailed introduction to the classification of low-frequency transformers and explore their applications in different fields.low-frequency transformerClassification of low-frequency transformersLow frequency transformers can be classified into various types based on their structure and working principle, mainly including the following types:1. Core transformer: Core transformer is the most common type of low-frequency transformer. It uses a ferrite core or iron core as the magnetic circuit and achieves voltage conversion through winding of the coil. Core transformers have the advantages of small size, light weight, high efficiency, and low temperature rise, and are widely used in various electronic devices.2. Shell type transformer: Shell type transformer is opposite to core type transformer, with its magnetic circuit lo...

In the era of rapid development of modern technology, switching power supplies are ubiquitous and serve as the "heart" of numerous electronic devices. So, how do we determine whether a switching power supply is qualified? This is a very crucial issue. Follow me, decrypt new knowledge today!500W Single Output Switching Power Supply1. Appearance inspectionFirstly, we need to conduct a visual inspection. A qualified switching power supply should have an intact appearance without any damage or deformation. At the same time, each interface should also be firm and reliable, with no signs of looseness.2. Performance testingSecondly, electrical performance testing is an essential step. We need to measure the accuracy and stability of the output voltage to ensure that it fluctuates within the specified range, and the ripple size should be controlled within a reasonable range. This is like the pulse of a power source, it must be stable and powerful.3. Load testingFurthermore, load capacity test...
