"It is a bomb electronic bomb which can blast at anytime" I was laughing on my a** up.. ! it was so funny.! however, I agreed on what you said as it can go off anytime as you over loading it.

It's easy just buy one more 12V 10A SMPS and put in parallel. I have done this a few times and you have a great video on this too.

Though I have several questions on this setup. First, how do we ensure the load is drawing approx same power from each source? Might it cause the power drawn to be lopsided? And therefore, cause one power supply to damage or possibly even both because it is supplying power over its rated specification

It is a great pleasure for me to be able to follow you and learn, you explain very well, thank you for everything you do! Long life to you !

Excellent explanation, I have a question: regarding the electronics before the primary side of transformer such as ( full bridge rectifier, capacitors....etc ) aren't they all make low impedance which would draw high current if we don't add a limiting current resistor at the input of the power supply?

honest suggestions, v good, it is better to buy new one for 15 amps. actually in our country people use 12v dc baleno motor for air cooler with computer power supply or some kind of 10a china ps, 15 or 20a china ps is costly, so they remain curious abt amps, bcos baleno +water pump works good on 15 amps ps, and 15 amps computer ps is low cost but when it fails then mechanics refuse to repair it, they said it is irreparable, its main ic is damaged.

These things are so "cheap" anyway. It pays to get two in parallel or the correct one. Depending on how much reliability you need, or your application, it wouldn't be too foolish to change the capacitors with those from a reliable source, even if the supply is new. It seems the other parts in cheap SMPS's don't fail nearly as much. Thanks for covering this. Best regards!

Hi, if the power supply is designed to run on both 120V and 230V, at 120V the primary works with double the current to get the same output watts, is that correct? So, working only at 230V, if we increase the output voltage (for example we duplicate it), would the primary and the transformer be able to withstand double the output power? I know that the secondary should be modified to withstand the new tension.. Thank you and best regards

Did you ever work on making a dual rail supply by separating the secondary into two coils and making them in series? (We must use balanced load otherwise in load regulated at positive section,the negative section will increase its voltage... Anyway let me know if it is possible...

@HaseebElectronics

Жыл бұрын

Good evening yes dear it is very simple. we need to analyze the load properly, then design the smps transformer using proper apparent power method, in this technique, the secondary will stable, otherwise the outputs will imbalance and the transformer will heat up, if we calculate the load properly then no need to put balanced load on both rails. each winding will run its own load safely

Jazakallah bhai for the video bhai. My case is contrary to this one, I used your method of adjusting smps voltage output to decrease 32v 3A adapter to 14v, but it only works once with the load, if I remove the load and reconnect it, it won't power the load until I unplug from main 220v and reconnect. Pls can you explain what the problem is?

I guess its better to go in alternative ways by combining 2 ps as you described in parallel or series configuration for more current or voltage is needed.

Yeap I agree. To upgrade those components or to buy a bigger one. How do you feel about using a resistor to ground? For example tying the sense line of a pwm with a low ohm resistor like 1 ohm to ground. I am trying to understand the logic behind the resistors value.

I have a 12V 15A SMPS. When I use it with a Car radio, there is too much Eletro magnetic interference and very hard to get a good fm reception. When I use the PC power supply for it, I have no issue as such. Can you explain the reasons for this and how to minimize EMI on SMPS ? Thanks in advance.

Please Explain can we convert 110 smps to 220 smps explain with Digrame you are working very hard pray for your Success

It is very easy to increase current, just buy a 300W version of the power supply, or better yet make it a 1KW unit so you would have spare capacity!... Another solution is to buy more energy efficient transistors for your projects that require less energy....

hi Haseeb...i am using an smps 12v 5amps power supply...i do not want any modifications done on the smps...is there a circuit i can connect the output of the smps to increase the smps amperage from 5amps to 8 or 10 amps with the same 12v output? thanks for the video.

Scootky diode kafi jyada heat hone ka kya reason ho sakta hai self made power supply me.

sir i have power supply of 12v 12.5 amp , voltage is variable , from 10 to 15 volt , i use this power supply to charge a 50Amp lead acid battery, but whenever battery is deeply discharged the power supply start charging it with current greater than 12.5 amps which leads to trigger overload protection of psu, i want to make the charger current variable and which should be between 1 to 12 amps, the power supply is MeanWell brand model no. RS-150-12

Haseeb bhai good morning, thank for your more valuable video, what is testing for this component, part no.is K45 NGD8201AG, 3leg, please make video as soon as possible

Hello sir plese help me mene ek 12v 15amp ka smps design kiya hu flyback topology wala .. Isme voltage and current proper mil rhi hai but but output wala scootky diode kafi heat ho jata hai kuch hi second me .dono side snubber network bhi use Kiya fir bhi heat ho rha hai. 20100 diode use Kiya hu.

I tried it many times, either on chinese PSU or ATX, the result was always poor and deceiving at loads. The best way is to do like in M Haseed video #598, put some PSU in series, the result is there !

Pensaste un una solución plausible? tal vez usando una fuente de alto wattaje 400watts, en la que el fabricante especifique salida de 12 volts 15 amperes y modificarla para hacerla de 30 volts 6 amperes y que podamos variarla y controlarla con tension y limite de corriente con tl494 y lm339 no modificamos tanto.
