- in this video number {794} Which One Is Best. 1x 400V. OR 2x 200V, capacitor in series. in last video number {792} i demonstrated how to convert 110 Volt xbox 360 Power Supply To 220 Volts operation. i modified CPA09-010A charger that is 110v operated, i explained process to convert to operate it with 220v ac operation.

Thank you for the explanation
Appreciated
Continue the good work
it is my pleasure
the way Haseeb sir is explaining the different types of circuits is like the digestive system of the animal. Food in , stool and urine out. In between the two working of other parts of heart liver and kidneys etc.
ordinary machenics like me learning a lot of things from you. without any degree of engineering we feel like we are the one who could do any thing. ..like in repairing and projecting some programing some circuits like fm. .amplifier. .radio frequency etc. ...
thanks a lot dear brother Tahir Ahmed
your words are really a golden asset for me
please accept my best regards
THIS IS DETAILED VIDEO. WHEN I WATCHED THIS VIDEO.I ALSO THINK WHY THE OUT PUT NOT DOUBLE.BUT YOUR EXPLANATION IS REALLY GOOD.THANKS SIR.
Thanks and welcome
It is a great explanation.
Thank you very much. Good night 🙏
You are welcome dear brother
Great explanation! I have used capacitors in series before in a tube audio amp and found that unless capacitors are perfectly match one capacitor can have much more voltage than the other. I'm not referring to this project, but in general. My project involved having to use balancing resistors to get the voltages across the capacitors to match. Best regards!
i believe you are right even when you say you increased too much the capacity... i dont tink there will be surge current because you have the NTC before limiting the current and its a low amperage psu so i think we are safe
You can always measure if theres any surge!
thx for one more great explanation never thought 110v worked like that also
Thank you
Thanks.
Görüşlerinize katılıyorum. Siz tecrübe ve deneyimli bir mühendis 'sin . Sağlığınıza ve başarınıza dua 'cıyım.
Allah sizi korusun ve mutlu kalın
Thank u so much.
You're most welcome
Very nice expy. Thank you sir
it is my pleasure
Thank you.
it is my pleasure
Excellent Opinion, I Also Agree With U, Thanks Brother.
So nice of you
Very good and useful information sir thanks
best regards
Please how did you get the value 1.414 that you used to multiply the 220volts
Assalamualaikum the video is very good. Thank you very much. Inshallah, I am waiting for your next new video, stay well, a
Thank you sir👍
most welcome dear
Well said!
thanks a lot
Thank you very much sir
it is my pleasure

Excellent Job Big Thumbs Up # 22
it is my pleasure
Thanks Sir............
thanks for sharing
most welcome
I'm like mashallah excellent superb informative vedio that's awesome great information you have entered best wishes good 👍
Thank you so much 😊
Sir, What is the cause of one resistor of SMPS heating up. (24Vdc, 6.6A,160W)
It works well, but it gets hot after a period of operation. I don’t know why. I noticed the same problem with xbox one adapters. big caps and transformer and output mosfets and caps is coming hot Thank you, Brother Haseeb. I hope you have an answer.
Thank you brother Haseeb. We learn a lot from you. Where are you from, by the way?
Most welcome dear brother
Thanks for your encouragement
I am from Pakistan and now in Jordan
Grazie ❤️👍
best regards
The parallel combination is much more useful than the series connection for the following reasons. If you make the capacitor values small enough, but have many, you now can use several SMT capacitor rather than a large thru hole device, which will reduce assembly time. Also, capacitors in parallel, depending on the PCB design (minimizing inductance) and assuming the use of SMT devices, allows a paralleling of capacitor ESR which reduces the overall value. There is one condition in having many parallel capacitors in close proximity, that is of the required airflow around each device for cooling. So, preferred is to have the capacitor bank have only two rows of devices with a small spacing between each (which occurs even if you butt the SMD footprints).
Nice
Dear Sir, I take care about the Energy stored and ESR of series or single capacitor used. That defines stability of the system and voltage stress over power transistor.
Allah bless you brother good work 👍
Many many thanks
Sir ,1st diagram used 4 rectifier why not 2
Awesome video dear friend, have a happy evening 😊
best regards and special thanks 💗
Hello mr how are you thanks for the valuable informations. Does this modification works for all 110 volts smps?
most welcome brother
if the power supply have this type of circuit configuration, then this method will work
sir does it working as voltage doubler circuit principle so that it convert 110(155 pp) to 311 voltage by using 2 capacitor s. sir if i m wrong please pardon me.
you are right. it is voltage doubler method
Good 👍👋👋
thanks a lot dear friend
Aslmuailkum brother
👌👌👌👍
best regards and special thanks
Lk 144 brother 👍👍👍
aleykum selam bro
modifiyeden sonra zaten gerilimin yükseldiğini ve gücün daha basınçlı bir şekilde iletileceğini de hatırlatmak isterim ! bir de fazladan 120 mikrofarat da ekleyince daha sağlam oldu 🙂

thanks a lot dear sister
I am not sure I will agree with the argument of ESR matters here. Given the application of these high voltage capacitor mainly filtering 50 or 60Hz main AC current after rectification, whether the ESR value is important or not is up to debate. I don't think ESR values matter too much here, rather the ripple current rating of these capacitors is important. High capacitance capacitor tends to have higher ripple current rating, so I think two 330uF/200V capacitors connected in series has its advantage as well.
The fundamental question here is why Microsoft designed this 110/120V power supply with two 330uF/200V capacitors, instead of just a single 330uF/200V with a full bridge rectifier configuration. This is a typical voltage doubler circuit, reminded me the old, dual voltage SMPS in many PC power suppliers and home appliances. Without any proof, I only can guess that Microsoft intended to have the same design for both 110v and 220V configuration, with minimal changes during the production process, just few jumper wires and a MOV. If such guess is true, the two 330uF/200V capacitors connected in series, with equivalent of 165uF/400V, is perfectly within the design specification for 220V application for this power supply.
The original circuit, using the two 330uF caps in series, is a classic voltage doubler circuit. Each half period charges one of the two caps only. Then their total voltage/energy is fed to the circuit. If we apply the formula for the energy stored in each capacitor, this will be 3,983 Joules, for 110V mains voltage, making a total of 7,986 Joules of energy offered to the circuit. This means that if we use full wave rectification, but with a line voltage of 220V, according to the same formula, we simply need a single capacitor at the half capacitance of the originals, that is 165uf. This cap will store the exact amount of energy as before (7,986 J). Now, as this value (165uF) is not a standard one, we need to choose the next higher capacitance value, that is 180uF, working this time at 400V of course.
The same modification, but in reverse way, can be done on a European psu, working on 230V, to work on 110V. Simply we instal a voltage doubler at its input, after removing the full wave rectifier, installing now two caps in series, having double capacitance value than that of the single one used originally. The key point in such modifications is the energy storage of the input circuit, which should always be the same (as it was originally designed, before the modification).
This process has nothing to do with parasitic inductances. The primary side capacitors work on low (line) frequency and do not suffer in the way the secondary side caps do.
Expained very well.
