Analysis of the principle of switching power transformer
The magnetic material used in switching transformers is soft magnetic ferrite, which can be divided into MnZn series and NiZn series according to its composition and application frequency. The former has high permeability and high saturation magnetic induction, and has low losses in the mid and low frequency ranges. The magnetic core has many shapes, such as E-type, E-type, EC type, etc

Improvement Method for the Problem of High Temperature Rise of Switching Power Supply Transformer
During the working process of switching power transformer, engineers not only need to comprehensively consider the rationality of its design and construction, but also need to strictly control its temperature rise range to avoid the problem of excessive temperature rise leading to reduced working efficiency. In practical applications, excessive temperature rise often occurs in both the MOS transistor of the power transformer and the transformer design itself. Today, we will start from these two aspects to see how to effectively solve the problem of excessive temperature rise in switching power transformers.
High frequency transformer principle
High frequency transformer is the most important component of switching power supply, and the ratio of turns of each winding coil of high frequency transformer determines the output voltage. It is a power transformer whose operating frequency exceeds the intermediate frequency, mainly used as a high-frequency switching power transformer in high-frequency switching power supplies. The transmission power is relatively large, and the operating frequency is relatively low; The transmission power is relatively small, and the operating frequency is relatively high. In this way, there are differences in both operating frequency and transmission power. The design methods of power transformers with different operating frequencies and grades are different, and it should also be self-evident.
Application Scope and Characteristics of High Frequency Transformer
I. Applicable scope of high-frequency transformer: High frequency transformers will be used in the dry cleaning industry. Bijing steam cleaning is cleaner and more effective.
