How LEDs Were Invented？
The invention of LEDs (light emitting diodes) was a multi-stage process involving contributions from many scientists. Here are some key historical moments in the invention of LEDs: Early theory and experiments: 1907: British scientist H.J. Round first observed that the semiconductor mate...Read more -
Why LED can emit light？
Light-emitting diode is a special diode. Like ordinary diodes, light-emitting diodes are composed of semiconductor chips. These semiconductor materials are pre-implanted or doped to produce p and n structures. Like other diodes, the current in the light-emitting diode can easily flow from the p p...Read more -
The role of electronic transformers in power supply technology
Electronic transformers and semiconductor switching devices, semiconductor rectifier devices, capacitors together, known as the four main components in the power supply device. According to the role in the power supply device, electronic transformers can be divided into: (1) Power supply...Read more -
Circuit board transformer magnetic saturation
What is magnetic saturation of a transformer? When the external magnetic field keeps getting stronger but the magnetic flux in the transformer doesn’t really change, it means that the transformer has reached a point of magnetic saturation. When this happens, any changes in the magnet...Read more -
Calculate the number of switching power supplies required for LED display screens
As the application of LED display screens becomes more and more widespread, the electrical parameters of LED display screens are increasingly valued and concerned by consumers. Everyone knows that LED display screens are made up of LED modules one by one, and the back of the screen is connected t...Read more -
Causes of high frequency transformer temperature rise and how to solve it
When the temperature of each part of the high-frequency transformer exceeds its allowable range for a long time, the insulation of the high-frequency transformer will be easily damaged, which can easily cause high-frequency transformer failure or accident. So what are the reasons for the high-fre...Read more -
The harm of continuing to use aging transformers
In the field of electronic devices, high-frequency transformers are important components that transfer electrical energy from one circuit to another. These transformers, also known as SMPS (switched-mode power supply) transformers or switch transformers, are commonly used in various applications ...Read more -
High frequency transformer to prevent aging
In electronic devices such as LED drivers, switching power supplies (SMPS) and printed circuit boards (PCBs), high-frequency (HF) transformers are important components that help to efficiently transmit high-frequency electrical energy. Like any other electronic component, high-frequency transform...Read more -
Internal and external shielding of high frequency transformers
Bad shielding doesn’t really affect the performance of high-frequency transformers, but it does cause a lot of interference to surrounding electronic devices. This is what we often call EMI. With the continuous advancement of technology, there has been a growing demand for high-frequency tr...Read more -

In the manufacturing process of horizontal high-frequency transformer, coil and magnetic core winding, assembly a...Read more -
Why do transformers need to control temperature rise?
Transformers are like the MVPs of electrical systems, transferring electricity from one circuit to another. They come in all shapes and sizes, including high-frequency ones made by fancy transformer manufacturers. One big factor that affects how well a transformer works and how long it lasts is i...Read more -
Leakage sensing and temperature rise of high frequency transformer
The leakage inductance problem is generally related to factors such as the wiring arrangement rules of the winding, the thickness of the interlayer insulation, and the width of the winding. There are generally 5 measures to reduce leakage inductance: 1. Each group of windings should be closely a...Read more
