Several issues about high frequency transformers [Copy link]

Several questions about high-frequency transformers I have worked on AC-DC products for a while, and I have also tried to wind high-frequency transformers, but I have never been able to grasp the air gap, compactness, noise, leakage inductance, aesthetics, etc.! I have always been unfamiliar with the design of magnetic components. How can I make up for this shortcoming? What are some good ways to get started quickly? Now I see that some high-frequency transformers have been miniaturized and surface-mounted. The manual winding and semi-automatic winding of traditional winding transformers are gradually replaced by fully automated high-frequency transformer production lines. 1. How to quickly learn the essence of magnetic high-frequency transformer design? (Don't need a bunch of calculation formulas. Learning the design at the application level is enough to support your family.) 2. The original power chip manufacturer will provide transformer winding process drawings and even design instructions. Do you do it according to the ready-made ones, or do you have to calculate it yourself based on a bunch of parameters such as inductance and frequency? 3. Some will provide EXCEL design software. As long as the basic input and output parameters are entered, the entire transformer parameter design can be completed. To what extent can this method meet the needs of product design? For the electronics industry, high-frequency transformers are very special components because they are customized, not universal components like chips, resistors, capacitors, diodes, transistors, etc.

Also try to bypass the high frequency transformer?

How is it done? What idea is it based on? Or what are the principles and steps?

PI should be in 2016, a transformer design software was released, the results can be obtained by inputting parameters

You should also be able to find PI Expert

A complete design of high frequency transformers can be performed, including core size, number of coils, appropriate wire gauge, and parallel windings for each winding.

First of all, we need to understand the principles, electromagnetic field theory, magnetic materials, circuit working waveforms, etc. Formulas are inevitable. If we don't understand the principles, it is impossible to design a transformer only by design software. When learning electronics, don't reject theory.

When learning electronics, don't reject theory. Calm down and learn mathematics, electromagnetic field theory, circuits, magnetic circuits, analog electronics, etc. Without these basics, you may not be able to understand a book on switching power supplies.
