The course of power electronics is really like a mystery, and I have no chance to practice it. I want to develop in the direction of power supply design. What is the best way to learn it?

You can use simulation software, which may make up for it. It is also possible to make a mini version yourself.

I don't know how to learn it, I just provide some of my personal experience for reference only

I didn’t really understand power electronics when I was learning it, but after I finished my graduation project, I felt it was quite simple (it’s hard to master it, so it’s hard to master the industry), so I still need to get my hands dirty. For hardware design, I feel that it mainly depends on two things: 1. Experience. A lot of experience accumulated over a long period of time is very important. Both experienced and expert people have accumulated experience; 2. Mathematics. Mathematics is essential for good designs, especially calculus. In fact, many designs are very sophisticated, but they just can’t calculate the specific values of resistors and capacitors and end up with nothing.

To sum up, I personally think that the direction of learning is: to lay a solid foundation in mathematics, do more design and practice, and learn to draw experience from mistakes.

Damn it, I just typed over 200 words and the network card didn’t send it out. . . . . . . . . .

Let me briefly talk about my personal understanding, for reference only

1. Learn mathematics well, especially calculus

2. You can’t do it without hands-on experience. This industry requires a lot of experience, and the experience gained from failure is extremely valuable.

The fastest way to learn is to memorize. To learn a piece of knowledge, first you need to remember it in your mind, second you need to be able to use it skillfully, and third you need to integrate it into your mind.

Find a mature and successful design case, read on, and when you encounter a problem, look for relevant reference materials. After solving the problem, continue reading. If you can fully remember the successful design case and use it skillfully, you will feel that you have learned it.

My network is too bad.

If it is product design, most designs have ready-made calculation formulas. You can calculate the results by substituting the values into the formulas. However, many parameters are not uniquely determined. How to choose appropriate parameters, how to determine the initial conditions, and the scope of use all require experience.

If you want to develop new products and improve performance, you need to use mathematical knowledge.

"Power supply design" depends on what kind of power supply it is. Power electronics specifically refers to the application fields of high-voltage and high-power electronic technology such as power generation and power transmission and transformation, while the "power supply" in the general context does not belong to power electronics, as power and voltage are far different. Common power supplies in the general context include computer power supplies, digital product power adapters, etc., and their technical requirements have little to do with power electronics. The technical foundation courses to be studied should be the basic simulation part of electronic technology.

In addition, there is a column in the power supply technology column of this site to guide beginners to learn power supply technology. It is recommended to check out the old posts.

The subject of power electronics sounds a bit complicated, but in fact it is about mastering how to convert, control and apply electricity. You have to lay a solid foundation first, such as circuit theory and analog circuits, and then have a deep understanding of conversion technologies such as AC/DC and DC/AC. Although there are not many opportunities to actually do it, you can practice with the help of simulation software, which can also deepen your understanding of theoretical knowledge. Want to design a power supply? There is a little trick, which is to use those code-free power chip design tools. They are like "little assistants" with a graphical interface. You only need to simply click and drag, configure it, and you can complete the design of the power circuit. This is especially convenient for beginners and can quickly get started; for veterans, it can also improve efficiency.

Converting AC to DC is rectification and filtering, and converting DC to AC is inversion.
