Flyback power supply novices, look here, the open source project is ready, it's time to get started~ [Copy link]

 

Hello~ Friends who want to learn about power supply~ Good morning~~ Guan Guan will go to "purchase" for you these two days~

Last time, I sorted out a wave of books and video tutorials for beginners to learn about "flyback power supply" . Did you seem to learn it? ?

Some friends pointed out that it is not enough to have knowledge reserves, we have to use them to consolidate them in practice. So, Guan Guan started looking for suitable open source project materials~~

Open source projects are being released gradually~

( The porters are still collecting, so let's start with the parts that have relatively complete information. We also welcome more friends to join us and post to share your open source projects in the power supply field~~)

I thought the forum was going to hold a replica event, so get some sponsorship to do it.

You can consider it. Let's see which one you want to fix, and then we can talk about the next step.

I have several broken 48V switching power supplies, but I don't know exactly what's wrong with them. What applications can I use them for?

If you have good hands-on skills, you can replace all the lights in your home with LED lights, so that power is not wasted.

Let's use our imagination to see how we can fix it.

Very good, thank you for the summary

The size is a bit large, and the LED power supply is a bit heavy

I am also interested in switching power supplies and want to make one myself, but I am discouraged by the thought of inductors and transformers. I hope the moderator can help me.

It doesn't matter, we will learn Ant Moving from little by little and start playing. You can call the manager to collect and organize what you have learned and what resources you need. Activities cannot be held all at once, but we can first look at everyone's key needs and then move forward step by step to see how to do it.

Is there any power supply design in the O-tube library? Input: 650VDC ~ 1200VDC, output: 450VDC

This is very specific. I don't know if it exists. I'll try to find it. If it does, please leave a comment under your post.

What are you trying to do?

The end product is a high power inverter/drive with high voltage input.

The input voltage was 380VAC before, but now the input voltage has increased, so the input voltage is rectified and then reduced to 450VDC.

Understand, just do some basic classic topology, which is easier to implement and easier to get started

Is it okay to disassemble the device while paying attention to safety? Disassembling the relevant circuits can also allow people to see possible problems. If they can be repaired, that's good too.
