{598} Connect Power Supplies in Series to Get More Voltage / Two or More Power Supplies in Series
HTML-код
- Опубликовано: 6 май 2022
- in this video i demonstrated how to Connect Power Supplies in Series to Get More Voltage / two or More Power Supplies in Series. i shared the series connection circuit diagram with practical demonstration. in this process we connect power supplies in series (head to tail rule) -ve of first power supply will taken as common (return line) and +ve of first power supply will taken as a +ve output voltage,
the same positive output is connected to the -ve of the second power supply -ve terminal. and the positive of send power supply will taken out as second +ve output section. and the same +ve will connected to the -ve terminal of the third power supply and +ve of the third power supply will taken as +ve output. thus all power supplies will come in series
so in series connection the voltage will added and the current will considered equivalent to the minimum current capability in series

amazing idea
thanks a lot
on some of that type of power supply the output -ve is connected to the earth/chassic so that set-up wont work. I can do what you did on the psu that uses the 2 pin figure of eight power cable since thats just double insulated and not earth, so its worth checking if the -ve is connected to the earth cable, I know you have already done that else yous wouldnt have worked but this advice is more for the audiences
fabulous
it is really a valuable point
please accept my best regards and special thanks
good comment. it would be cool to hear an explanation of how/why it works that way.
Best for technical education and problem sorting knowledge .
Salaam alykum. I watch your all videos. Very informative . Allah will give you best rewards

So, can I build an inverter machine of 60v, 20A and add three of these to summe up the current? Thank for you instructive videos.
Allah aap ko hifzo amaan me rakhe ,,, Jazakallah khairah ,,,,, 👍
Aameen

hi there, can we use the input and output reverse method in SMPS of 12v 10a, like giving 12v 10a dc to output to get 220 v ac output in SMPS? thank you
Very interesting. Thank you.
thanks a lot
it's never too late to learn!! :D
Thanks for this!
now, I have a question..... is it possible to use separate AC inputs for each PSU.....??
can we do this with power banks, connecting them in series to increase the voltage?
Assalamu alaikum, it's very useful practical Electronics video
Thank you very much

Awesome video dear friend!
thanks a lot dear friend
Excellent video Sir ❤️
best regards and special thanks
Very good.
I just wanted to know the amps when doing this, thanks!
I want 48v 20amp output.
Which would be the best that,
Connecting two 24 v 20amp in series. Or
Connecting two 48v 10amp in parallel
Hi this video also very useful but I asked one question, how to make +12V. 0V -12V from any single or two smps using.
hello sir i have 2 smps with 24v but the amps ratings are different one have 10 and another have 15amps i want 48v output so can you tell me how much amps i will get at the 48v ? and both power supplies are different from each other 24v 15a is a ultra slim one and 24v10a smps is traditional one .
I have a power supply with double output voltage. 32v/1a and 16v/0.5a with common black negative cable and two red positive cables. I want the sum of two voltages 32v + 16v = 48v. How can I connect the two voltages in series?
wow really great videos
thanks a lot
Sir is it possible to convert a SMPS of input 220vac to input 110 vdc.
So i learned something today. Amps are limited by the weakest link. I am left with a question; what if your series connection started with the 6A power supply? By your wording, the effect should be the same. however a confirmation that its not 25A would be cool.
and would that require wiring in parallel instead then?
Thats a good video
best regards
What happens if you connect together 12 v line and 3.3 v line of a single ATX PSU sir , will it blow?
Yeah you did it :-) Your teaching these boys & girls some great knowledge well done,,,
thanks a lot
Good one...
best regards
thinking of cleaning some better pulse with many paralel but if they synchro the pwm then it will be more powerfull so need many ... same specs but different htz
lk thanks for sharing brother

Hi I did exactly as you describe your video and I cannot get it to work I was trying to add does voltage from a 19.5 laptop power supply I checked both power supplies before tried to put them in series and all it would do was make a clicking noise and put out .6v to .20v do you have any idea where I could have gone wrong
as i demonstrated practically and explained every step in detail. so it is working method. moreover i use this method most of time in my routine work,
if you are trying to connect laptop chargers in series. may be it will not work properly as the laptop chargers have id sense system.
hello i do not know much about power supplies, I need 24v and 1.65 amps but my buying a 12v supply rates at 10 amps. i dont know how many 12v output it has but if it has 2, can they be connected in series to make 24v or should i buy 2 12v supplies
if you want to add voltage, then you need to connect 2 power supplies in series
Super nice 👌
thanks a lot
lk superb🌹🥀🌺
Many many thanks
If all the power supplies don't start up (or don't start at the same time), would the reverse polarity voltage potentially applied to the non-started -up power supply potentially cause the output capacitors to rev polarity and explode? Would it be good to put a diode across the output of each , rated for at least the total combined voltage and rated for the current of the highest current power supply?
wow
i salute to your valuable point. i have to study it and will discuss it surely
please accept special thanks and best regards
@@HaseebElectronics look forward to your thoughts. i'm guessing that the output circuitry may offer some protection against this already , but that diodes may offer cheap extra protection for edge scenarios with unusual loads etc..
...and in fault conditions such as short circuit across load which means the power supplies output will be connected in opposite polarity.I agree that it is a good solution with Schottky diode connected in reverse bias across output terminals of each power supply. This is for two power supplies. I haven't considered what would happen with three or more, but I think it would complicate things even more..best regards.
And if I understand correctly, the ground-leads of each case lead to the wall-plug, but out of all the ground-connections of all the boards to their respective cases, you have to leave just the last one untouched. All the other board-to-case earth-connections have to be capped...(???)
@@klausbrinck2137 Very good point . Most purpose built SMPS (eg MeanWell ) do not tie the Negative output to the mains protective earth, or to a metal chassis that itself is connected to protective earth. I don't recall ever seeing a manufacturer recommend this, nor do i recall reading them advising against it either..
In units where you see this negative DC to protective earth bonding inplemented, (such as in surplus HP proliant server power supplies ) , this connection is most typically removed. There are blog posts and videos on you tube detailing this.
now ,.. you could choose to leave the earth connected on the first (lowest potential) power supply , within a series string. I can see potential benefits - as well as potential downsides - to doing this, but in general for battery and solar type applications I believe the choice is most typically in favor of full isolation . (Whereas in the computer world I think it may be customary for the chassis to be tied to DC negative / i.e. zero DC volts.)
You should decide what you want and configure accordingly.
Salam bhai
If we connect output of same supply in series will it increase the voltage??
These are really helpful videos....many thanks!
You are welcome!
SIR CAN USE THIS FOR 24V (3A) RO SMPS , sir i want to convert 2 24v smps into 48this will work?
Lk 152 brother 👍👍👍
Many many thanks
can you make a video of connecting 48v power supply to make 48v 100amps or bigger apms?

What if the ps3 is 25a ?? It will be 36v 25a ????
Hi sir,
I had a 24inch Samsung led tv power supply.In that +5volt,led driver volt is ok.only +12volt is flickering when I connect any load.rest of the voltage working well with load,
I had tested this circuit with 12volt 35w lamp with 5v it's glowing without any voltage drop,in 12volt side it's not even glowing little flickering with smps noise?
Suggest me a solution to repair this problem?
please check the capacitor in 12 volt line, i think the 12 volt smoothing capacitor is making problem
for good suggestion , it is better to send tv model number or the PCB model number
@@HaseebElectronics ua32eh4000r hi sir,this is the model number of the tv.please check and revert.what might be the issue?
? sir any information
Smps pcb number:bn44-00492c
Yes very good. But doesn't putting switchmode power supplies in series to add voltage have some weird affect on the regulation? In other words it sort of works, but the regulation
can also get weird. Ever hear of that? Linear supplies might work better for series connections between supplies. What do you think of that?
thanks a lot
it doesn't effect on regulation. as the feedback regulation circuit have to sense the potential at its output terminals. it have to produce output
if it is grounded properly, then it is safe and works perfectly on load sharing
I do this all the time with iron core, smps, and even smps based lithium ion battery chargers. No issues. The only weird things I've seen is when paralleling the output of chinese DC/DC buck/boost modules.
I advice to use PSU with "remote sensing" option to balance the voltages over the load
yes dear you are right
but these cheap industrial power supplies don't have remote sense or remote adjustment options
these have standard output terminals
so when we want to cascade power supplies for temporary use, then this option can be used
otherwise for a long term operation it is not recommend, not safe and not long lasting
Csn we get 12 0 12 out of 12v smps i mean ground -12 and +12v ?
if it have center tapped winding, then we can get dual power supply
or if we have 24 volt power supply, then we can split it into 2 portions, but in this condition we will take virtual ground
@@HaseebElectronics you mean a transformer?
@@HaseebElectronics i have center taped winding. Actually a circut board for same purpose but it never worked and i cand figure iut why. In that circut 2 mosfits irf150 and tl494 ic is used
I must be doing something wrong because it keeps smoking one of the PSUs . I can't understand why its not adding the voltage in series. I have two 60v / 25a PSUs and am trying to get 120v combined output....
Please check the output side ground terminal (-ve or return line ) is coupled to earthing ground terminal of input side?
Please check eitther the output side negative terminal (low side terminal) is coupled to primary side safety ground or power supply chassis ground?
Can I send you a picture of how it is wired?
@@HaseebElectronics can you just post a photo of two power supplies wired in series with just a single positive and single negative output that would be double their voltage?
Hallo sir I have little problem my parallel power supply voltage is not same 1st one 23volt and 2nd one 26 volt what is happen I will connect togather is it 💣💥🤯 or work fine
in this situation it will not work proper with parallel connection
higher volatge source will cause to flow current in low voltage source.
@@HaseebElectronics ok so I have 50 amp bridge diode will it works shoud I gat 25.5 volt ....and also amp was not same one is 20 and other is 18😅 did I gat 25.5 volt 38 amp may be 😮
Is it possible to increase the amperage value by parallel link?
yes please check video number 597
@@HaseebElectronics thank you. It was in the previous video. ^^
Salam brother ...you thenk that is safety ...spcialy ..whene you charge a 48v battery? ...thank you
yes it is safe. as the battery have current protection so you can use it, just take care for the battery voltage and polarity of battery
@@HaseebElectronics thank you so mutch great channel .. good like
👍👍👋
thanks a lot dear friend
Hello :-) ... again 🙂
I have HP 12V Server Powersupply's, too .
When i modify that devices to 14V i have in Series of 4 = 56V TOP ( I need that voltage )
Now comes a Big BUT!
But the Powersupplys has 100Amp , that means i have than 4KW DC Power and i need ~ 5KW AC Power on one AC Fuse !
I need current limiting.
My Idea
ok either i limited each single power supply before series connection.
Or I limit the series connection.
Is there a current limiting circuit that works for so much power?
12V/100A or 56V/~100A current limiting circuit?
i try to charge with 80-100 amps/56Volt on lifepo4 ,
You can then see me charging my battery in google earth, the red glowing house In Germany/Bavaria.
And red lines, that's the AC lines...
I know I shouldnt promote other peoples channel without permission but jehu garcia use such a setup for charging some life batteries, cant remember if he is using 4 or 6 in series,
@@dantronics1682 ...the world is small :-) iam a subscriber from him ,too thanks
wow it is really great work.
but first i will recommend to use proper charging system for thos LifePo4 batteries for safety, as batteries are like a dynamite
1. yes you will need safety fuse
2. instead of current limiting, it will much better to arrange a battery management system (BMS) circuit to control and maintain the batteries.
wish you best of luck dear brother
@Dan Tronics it is really best to discuss with each other. and share ideas. when we share ideas and our experience to each other, it leads us to some perfect solution
special thanks for replying to @BavarianSuperGuy
@@HaseebElectronics I have a bms on it and it is save . the current limiting i need for start charging slowly like a solar charger. Thank You for your Video Work
Sir I have a query
NOOO, the load will no be evenly distributed this way. To do this right, you need a PSU with a REMOTE SENSING function, which will balance the voltages between the devices. Mean Well SE-450 series for example have this function.
It can be compared to using capacitors as a voltage divider. that won't work. Caps need resistors to keep the voltages balanced.
No. when we connected 2 sources in series, it works normal. it is as per my experience,
if we are using 2 power supplies, let's say 12V 10A, total voltage will 24V and current will 10A
if we use different current rating (12V 10A, and second is 12V 6A) total series voltage will 24 volt but the maximum current will 6 ampere. above 6 ampere it turns off)
@@HaseebElectronics what about putting the (dc) input in parallel? have you tried? I want to use it like that, is that possible? dc input in parallel and dc output in parallel (with remote sensing).
If not why not? thanks!
maybe you are talking about paralell conecttion not series :)_
@@radekzmazur3389 indeed parallel I was confused. and still am. it looks parallel, but it is series, if you look at the output capacitors.
voltage is higher.
PSU12v 10Amp + PSU 12v 30Amp= 12V 40 Amp work or not work
no
that will 12V 20 Amp in parallel. above than this it will 12V 30Amp only
because after 20 Ampere first power supply will meet its maximum limit, so it will shut down. and the total load will converted to the second power supply
Has to make sure the AC & DC grounds are isolated.
In series the voltage ⚡️will be 36 and the current will be 18.66 amp.
The average of total current
But the real question is: What is the power in wattage at each output. 12v at 25a is 300w. At the 24v connection, your power in wattage is 24v at 25a = 600w, what is it at the 36v connection? 377, or something else?
Asssalam alikum sir can u plz make a video on ac dc fan circuit
I learn that
current remain same in series but volt change.
in parallel current change but volt remain same.
exactly perfect
asslammualiekum
thanks sir. can you explain computer ups ,do you have time
i hope your next video
sure
i noted it and will try my best to explain it soon

How does mobile phone charger work and why the cord have four(4) wires
most chargers use only 2 connections of 4. some iphone chargers use the other connections to make sure it is a genuine charger and cable..
either the green or white wire is connected to a resistor which is grounded, some phone chargers have both data d+ d- tied together
there are 2 types of charging cables
1. *USB Charging cable* (it have just 2 wire, normally red & black for +5 volt & common)
2. *USB cable* it is charging cable + usb communication cable (Red & black wires for charging purpose, while white and green wires are for data communication between the mobile and the hosting device) the fifth one there is also a shielding braid which is connected to both side connectors and ground wire. it provides signal shielding and protects the communication loss and protects from uter interruptions
@Theseus perfect dear
@Dan Tronics
you are right inside a branded charger, data wires are terminated to ground but in low quality chargers these are left open ended.
so just like batteries!!
exactly it is similar to the batteries
