The frequency of electricity in daily life is 50Hz, which we call low-frequency alternating current. Transformer that works at this condition is low frequency transformer. Big size and low efficiency are the features. The iron core is stacked with insulated silicon steel sheets, and the primary coil is wound with ename...

High frequency transformer is the vital component of switch power supply. The transformer realizes the basic conversion of input and output voltages. On the other hand, it also performs high-voltage isolation at the input and output ends to improve user safety. In order to achieve high-voltage isolation of switching po...

When designing the high-frequency transformer, the leakage inductance and distributed capacitance must be minimized, because the transformer in the switching power supply transmits a high-frequency pulse square wave signal. During the transient process of transmission, leakage inductance and distributed capacitance wil...

Improving working efficiency is a common requirement for power supplies and electronic devices. Improving the efficiency of high-frequency power transformers can save electricity. It also has double social and economic benefits of environmental protection. Therefore, improving working efficiency is a major design requi...

Transformers are important in our daily lives. They exist in the electrical equipment related to power supply. Let's talk about something about transformers. 1. Difference between high frequency transformers and low frequency transformers In general, low-frequency transformer refers to "power frequency transfo...

When talking about the design of high frequency transformers, there are many things: design of coil parameters, selection of magnetic materials, selection of magnetic core structure, design of magnetic core parameters, selection of transformer structure, etc. Here are five key points for high frequency transformer desi...

High efficiency is a common requirement for power supplies and electronic devices. Improving the working efficiency of high frequency transformers can save power. It also has double social and economic benefits of environmental protection. Therefore, improving efficiency is a major design requirement. Generally speakin...

1. Working Principle High frequency transformer is a component that converts alternating voltage, current, and impedance. When an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core). At the same time, the voltage (or current) is induced in th...

In the comments section of major social media platforms, JRPanel is often asked about the air gap in transformers. So, in this blog, we will specially explain the knowledge of air gap to help you have a basic understanding of it. We all know that the air gap is generally used in flyback transformers. The flyback transf...

Hi guys, glad to see you here again! In previous JRPanel videos, you must have found that the high frequency transformer is always wapped in yellow tape. In this blog, JRPanel would like to introduce you the different types of tape used in High Frequency Transformer. 1. Mara Tape Mara tape, also known as polyester tape...

Hi guys, this is JRPanel ! In previous blogs, we have introduced several points about High Frequency Transformer, like bobbins and Flat Spiral Coil. In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers, based on materials. Generally speaking, the material of the core determines...

Hi guys, this blog is still about high frequency transformers. JRPanel would like to introduce you the main use of transformer bobbins and how we classify them. In the pictures are the transformer bobbins. Following are the main uses of that JRPanel has summarized for you: 1. The bobbins provide space for winding coppe...
