In many electronic application scenarios, people will use step-up transformers, but you may not know the working principle of step-up transformers, so it is very troublesome to choose.

Amorphous strips are mainly used to replace transformer core materials (silicon steel, ferrite), and belong to a new generation of transformer cores. Transformers can be divided into frequency power frequency (50hz or 60hz), intermediate frequency (60hz to 20khz), high frequency (above 20khz) according to frequency.

In many electronic application scenarios, people will use various types of transformers, whether it is a high-frequency transformer or a low-frequency transformer, the manufacturing process is similar. Next, Zou Gong, a senior design engineer from Shenzhen Yingzhe Technology Co., Ltd., will introduce the general production process of transformers.

The high frequency transformer is the most important part of the switching power supply. The switching power supply generally uses a half-bridge power conversion circuit. When working, two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, and then the high-frequency transformer is used to step down and output low-voltage alternating current.

Transformers and inductors are easily confused because they have the same physical shape. There is only one rule that can be distinguished between them, the transformer is marked with "QTK", and the inductor is marked with "QHP".
