24vdc power supply

[son0102]

Hello everyone, I currently need to design a circuit to convert 220VAC to 24VDC about 10A for my DC motor. Could you please provide me with some simple circuit references? I have searched the internet but haven't found many results. I have just started learning about power electronics. Thank you!

Hi,

First of all: Designing a AC/DC SMPS is not an easy task. From operation to noise, safety, local regulations, EMI/EMC ... schematics, PCB layout...
--> Nothing I would recommend someone "just started learning".

Now I´m a quite experienced elelctronics designer .. who did SMPS already. I would not do a standard 220VAC/24VDC 10A power supply design. There are so mayn good and also cheap ready to buy. This most probably results in reduced price, no development cost, all the legal things are already done, no risk for failure (if used according specification)

***
But if you really want to do so:
Every SMPS IC manufacturer provides all informations, like datasheet, applicationnotes, design notes, descriptions, example designs, development boards, formulas, tutorials, online IC selection tools, some even online schematic creator including all part values, some even videos ....

So for me such a general question makes no sense, since all the the information is available in huge numbers. Most information is more complete in one document than a forum thread could ever give.

A forum is mainly meant for more _detailed_ questions.

I think you have to use something like this. https://www.hannainstruments.be/en/220vac-to-24vdc-power-supply-hi900947/ You can buy and dismantle one to understand how to make one by yourself.

you could use power integrations PFC (hiperPFS) followed by their HiperTFS Two transistor forward......i think they give full instructions how to do it.
You know you really should use a Boost PFC stage up front?
Then go for a Two Transistor forward....or half bridge......or if you want go go simple, then do three likewise flybacks in parallel...and add some share circuitry so they all share the current.....or just current clamp each one to 3.33A.

But yes, what you ask for is a standard offTheShelf product, availabel at low price from multiplel sources, so to garner more info, you shoudl convince us that you really do want to design it from scratch.

If you want to just buy it, then try digikey, or meanwell, or TDK, or XP power, etc etc.

I hope you know electrical safety well. Its so easy to accidentally touch the mains.

Our languages are different..., watching the video I can't seem to understand. There are diagrams that are too complicated. I just need simple things to make it easy to find and buy components

Thanks I will consider it

thank you, if i can't i 'll buy them

The power of 240W is no longer suitable for beginners to make at home, as it requires a larger circuit structure and a wider variety of components, making it very cumbersome to purchase and install. And there are many solutions that can be achieved, suitable for different application scenarios. For example, whether the input voltage is pure 230V or 100-240V, whether it is continuous 240W or only requires instantaneous 240W, whether a plastic casing or a metal casing is needed, whether a fan is allowed, what is the required conversion efficiency of the power supply, what is the output ripple noise, whether PFC or additional protection circuit should be included, and so on. If you only need one or a small quantity, it is recommended that you buy a second-hand power supply with similar functions on an online shopping platform, which may be more suitable. If a large quantity is required and it is not a standard product, you can contact the power supply manufacturer.
