- In this video, we discuss the major differences between the two DC power supply types: Switching and Linear.

The 2:33 graphic contained a mistake. Since it is currently not possible to edit the graphic without deleting and reuploading the video, we have decided to blur it out.
We would like to apologize for the confusion and thank everyone who pointed out the mistake. - วิทยาศาสตร์และเทคโนโลยี
FYI - your summary slide shows the linear power supply as using PWM...and the switching PWS using a transformer
Oops! Thank you for the heads up. We'll try to edit this and re-upload as soon as possible.
@@KikusuiElectronicsChannel Don't forget ;)
@@KikusuiElectronicsChannel OMG... you confused me so much!!
Change it!
Before I even scrolled down to the comments section, I knew that there had to be a comment about this. And there you go, the first one!
I always use linear power supplies due to noise.
They are almost as clean as a battery, in many applications this is essential.
A lot of the background noise heard within the radio spectrum nowadays is caused by switching power supplies.
I have a couple that were made back in the late 70s and more importantly they are in almost daily use, you may occasionally get coil whine but this is easily solved.
Downside is they cost more money and aren't as efficient.
I do have a switch mode supply a thurby tsx3510, which is now at least 10 years old and proven it's worth.. over a grand new.
Like the video says. It all depends on what you want it for, but be sure to buy a linear if using RF or highly sensitive prone to noise interference circuits
fantastic video...short and to the point. Thanks!
Thanks for sharing . Simple and easy to understand
Excellent explanation...good job.
Hi, Very good video, I have two power supplies, one being switching and the other linear. When I use the switching mode power supply on an amplifier I built, I get all kind of distortion, however, when I use the linear power supply, the amplifier distortion is gone... You have helped to understand why this is so. Thank you for sharing this video...
Great this what I needed to know! I am a novice looking for my first dc power supply :)
Thanks, very useful!
Nice explanation 😎😎😎
Good info
Nice information... Thanks
good explanation thanks.
What about the switching noise of the rectifier bridge in the linear power supply and the typical 60hz/120hz humming noise?!?
Nice presentation and really great products.
But where in Europa (Germany) can I purchase your products?
Isn't it mistake on the image on 2:45? I think PWM is replaced by place with Transformer on the height of "How it works".
i was thinking that too
So what I gather for an electrolysis plating use linear would be the better option or does it not matter? Any assistance would be gratuitous.
thank you
the slide shown at the end seems to be wrong, transformer and pwm are on the wrong sides?
You know you're being hoodwinked, when he seller describes them as a 'UK Variable Linear Adjustable switch-mode Lab DC Bench Power Supply 0-30V 0-10A 220V'
Something is going to be dodgy, if it costs only £50 and was made in China!
So, which one do you use for working on audio electronics?
In audio electronics you usually have high frecuencies, so you better use a linear one.
For audio linear are considered better because of low high frequency noise
Cool
Thanks but there are some mistakes. Switching supplies are very fast - even your graphs show this. Also your table at the end shows PWM under linear supply:)
My vote.....go Linear. 👍
Video is great but the image is wrong. It states linear=PWM and switch=transformer. 👀
Switching power supplies can not be used in parallel meaning you can not put 2 of them to double the amp output. You can with regulated ones. Switching will start fighting each other.
Tem com tratusir em portuques?
Thanks for this but if you are not going to correct the mistake where you identify the linear system-ply as using PWM then you need to take the video down before you confuse even more people. You said previously you would, so why hasn’t it been done?
hi how abot the power consumption?
because I have linear and switching power supply, and iwant to use the lower current consumption.
tnx
Switching power supplies consume less power. and they are more efficient.
in the table there is one error. Linear not PWM.
I used a linear power supply for my laptop charger to charging battery , but there is a problem about connect / disconnected charging every second... why?
check amps
As several folks have mentioned below - the comparison chart which is displayed at 2:31 is incorrect. Leaving it uncorrected after folks have taken the trouble to flag it up, and after you've promised to fix it, and after 2 years has passed is irresponsible, and reflects badly on your company. The video is easily sorted - but a bad reputation isn't.
What is the correct chart? Thanks
@@j.lietka9406 On the 2:31 chart, the "How it works" row for Switching should say PWM, Linear should say Transformer.
@@RobDunsford ok thank you for the correct info! Any good word on a tacklife brand DC power supply? Thanks
Anyone who listened to the information in the video explained or has half a brain can figure out they 2 were just swapped accidentally. Nobody is really going to avoid the company over something stupid like that on social media. Get over it.
Unfortunately you can't "edit" a TH-cam video like that. You have to delete it and replace it with a new one -- the original is totally lost even though the change is trivial. So you lose the history, it breaks the links for people who have references to it, etc. It often just isn't worth it.
Graphics are misleading. Someone who knows about these supplies should be sitting with the editor and go over the video before uploading.
Where are they misleading?
@@altuber99_athlete Use the (electromotive) force, Luke!
@@altuber99_athlete 2:50
@@rb6725 Thanks. I see the mistake, where it says SMPS use transformers and linear supplies use PWM.
First line in the graphic at 2:51 is wrong - reversed.
is there possible convert Linear Power Supply to Switching power supply?
Why would you want to do that?
@Dimdim big brain
Linear is more expensive. Why would you do that?
NO.. It is a crazy idea.
Both options have their advantages and disadvantages? Blasphemy, (insert generic argument here)
you didn't edit the mistake yet ;)

*"... What's the difference?..."*
Weight.
I’m a rank beginner in the electronics field but knew something was wrong when I heard one thing but saw the opposite in the graphics. Irritating. After two years and no correction this is terrible advertising for whoever made it.
and your one sad puppy for humanity, sitting on social media and whning about something you dont understand.
exactly how should he edited it.?
he explains it in details so even you can seee what is up and down.. that one segment in the charts is flipped...yeah mistakes happens..but instead of saying thanks for explaining it, you hurry to whine about a minor graphical mistake. come on the dude just spend all the video explaining pro & c0ns so it doesnt take a phd to realize what benefits they each have.
dang.. characte3rs like you, gotta be one handfull to be around.
