- In this video I have made a powerful 200 Watts DC to DC converter capable of converting 11-15 volts DC into regulated 220V DC output by using the popular SG3525 PWM IC. The efficiency of this converter is around 85 percent for small to medium loads and around 80 percent for heavy loads of greater than 100W. The idle current consumption is only 80 to 90 milliAmps due to great feedback and control of the PWM IC
Interestingly you can power SMPS based appliances like LED bulbs, phone and laptop chargers and can even test small filament bulbs.
This module cannot run any inductive loads like AC motor or fan which requires sinusoidal AC voltage to operate.

Excellent work brother 👍
Thanks man!
Nice one brother... so good explanation. English is well. ❤ we can understand all the word you told in video. Do more videos. You have good future. Good luck. 💪💪💪
Thanks for the support!
I m from Pakistan really a nice and informative video keep it up 👍❤. Plz make videos in Urdu also thanks.❤❤❤
Good...
Tks, friend!
Thanks!
খুব সুন্দর হয়েছে। আমি অবশ্য ই বানাবো।
Thanks!
please make a video about : "how to calculate smps transformer wingdings" !
Sure,I will try and make it
Shouldn’t the high voltage ground be isolated from the low voltage ground that is feeding the IC and the gates? Or it doesn’t matter? And also can you also make one with the optocoupler feedback. Thanks
Awesome man... 👍
Thanks!
I am impressed
Thanks!
Excellent
Thank you :)
What the probelm when I build dc to dc converter with this pwm. When no load its normal, but when given load my voltage input drop (12v to 8v) ?
@@fikrialvian8098 that means that the current capacity of your source is not that much. When you connect a load at the output, there will be a higher current draw from the input and you will need a source that's capable of delivering higher current, for eg, a lead acid battery
@@UtsavShah_25 for your information. I have used a 75Ah battery. and the load I use is a 100 Watt or 5 Watt light bulb, it remains the same, the power supply shows the voltage drops to 8 Volts. I am confused about where my mistake is even though all the totem and switching components are not damaged when I checked. The ferrite transformer I use is the EE55 type. previously my circuit was normal, but there was an explosion incident so I now need to fix it but I am confused about where the mistake is.
@@fikrialvian8098 I think there may be a problem with the feedback loop that is used to keep the output voltage stable. Also check the voltage levels of the gate-source terminals when the load is attached vs idle condition. If you have a scope then it would be very easy to check this
@@UtsavShah_25 bro can you explain me the correct feedback circuit on this ic. I still don't really understand the feedback path of this ic. all I know is rotating the 10K trimport to regulate the output voltage.
Make a video on push pull ferrite transformer design
Okay will try and make a video on this concept
Please provide schematic diagram clearly
Thanks for your reply and I wont to your helpful for your support do it
What is the current output of this devise when output voltage is 330v?
Great video.
Did you know how to increase the power rating to 1500watt???
1500 watts may require hooking up multiple such transformers and more MOSFETS in parallel to increase the current capacity
This is has Overcurrent / Overload Protection? What will happen if we give any overload? Please reply brother.
you must have a resistor of to prevent overload or short circuit
Bro you are used EI-33 transformer.
I got EI-35 from a psu.
Can i use it with the same gauge wires and same turns?
You can use the same guage wire. However the turnings can be different as the cross section area of the core material has changed. You can use online calculators to get an exact value
I have a 40 volt dc to dc inverter (ic sg3525). how do I make my dc to dc inverter. so that it can be set to 12-60volt out?
You need to use a step up transformer and use potentiometer for feedback to adjust output voltage
Can we use insulated copper wire for both a winding?
You can but the insulation would not allow you to get the required number of windings on the fixed area of the bobbin
@@UtsavShah_25 ok bro, I done the project, I got the maximum of 280 voltage. Thanks for your help bro
@@arulprakashg2229 that's great!
What is the work of the other variable resistor
The function of the first variable resistor is to set the low battery cutoff voltage, the second one for the frequency adjustment( can be optional and be replaced with some suitable value) and the third one is for the output voltage feedback.
i want to used this to converter dc 12v input to -/+ dc 42v for audio amplifier so for feedback which resistor should i use and which wire should i use for feedback error correction, out of these, dc output of +42v 0v -42v?
thanks
Well to get dual voltage, the winding setup of the secondary side needs to change. The secondary winding should include a center tap which will serve as the ground. The output voltage determines the number of windings that are needed and since your requirement is 42 volts the windings would be much less, I need to calculate it though
@@UtsavShah_25 as i have ee55 transformer i am winding 4 volt per turn (3+3) and the frequency i am using is 100khz, which output voltage should i use for feedback?
42v is after full bridge rectifier
@@AbdulRahman-en3ow you can use online calculator for this
@@UtsavShah_25 and should i double the voltage (42v) as you're using half bridge to converter high frequency to 50hz
should i ignore the center of output (42v 0v 42v) and connect the outer two voltage to the half bridge, to get 50hz?
thanks
@@UtsavShah_25 can we use these high frequency voltage for audio amplifier?
What is the efficiency of this circuit??
About 75 to 80 percent
Only ferrite transformer design is main component in this design
Bro, what is the value of inductance and mutual inductance of transformer?
I haven't calculated that for this project
Vin*10 power 8 /4*Bmax*frequency*Area in cm square
Primary side 3 turns are wind opposite direction? Or same direction, what about sec w.r.t to primary side direction
Both primary and secondary are wound in the same direction
Hai brother, Please share the current rating in Ah in the 12v battery you have used?
12volts 17 Ah battery
@@UtsavShah_25 thank you brother, I have the circuit with 12v and 1amp output, is it okay with input?, or there is any particular range we need to use?
@@arulprakashg2229 yes 12volts as input voltage is fine
@@UtsavShah_25 thank you brother, nice project
Can we insulated copper for Both a winding?
Can Send me clear circuit diagram cl

You can find the schematic in this article
It's not working I've recently made it the regulator ic busted
You can check the connection for any shorts or faulty component that might have triggered high current surge through the regulator
@@UtsavShah_25 bro I've checked all there's no short circuit... But the regulator keeps busting and I've directed the supply with 10Ω resistor... The circuit is not working when feedback network is attached and...
Bro do I need to connect the output ground to circuit ground?
What is the value of output current in this project bro?
Depends upon the load but the recommended maximum can be 1Amp at 220V DC
I am interested to work best regards to you . sir.i am required to be a load power supply for hho kit how made it.i require to be a load of low voltage and higher ampier current load of 15to30ampier current load circuit board do it possible.i perched it's
For such high current requirement it is better to use a dedicated power supply capable of handling such high currents. My circuit is made to output higher voltages at lower currents
Sir please send me diteil for your kit price and to surruity this board to high current & higher voltage. DC to DC current send me detail. My WhatsApp no 8488899967&my email as a ashokpatel8501@gmail.com
@@hhogasproduction5081 This is just an experimental board and I am not selling this commercially. If you wish you can refer to the instructions and make one for yourself :)
What is the current consumption with 100watt dc 220v load ?
About 9.7 Amps
@@UtsavShah_25 so high.
I’m looking for schematic/design that use much less than 9A ?
Any suggestions ?
@@calico88 this circuit works with 12v as input. If you want 100 watts as output then it's not possible for the current to be less than 9.5 amps.
@@UtsavShah_25 I’m sorry, I meant 100mW not 100W.
Any suggestion ?
@@calico88 then it should not be more than 10 milliAmps
4 mosfed use karne ke baad bhi mosfet heat ho raha hai. 50khz pe
Iske liye kya kare
Please help me
Check the gate signal, it should be about 10 volts to properly drive the MOSFET. Also check the winding of the transformer, there should not be any shorts within the winding
Gate voltage 5.62
It should be 10 volts, it is better if you can check with a scope
60hz?
The output here is DC in nature, the switching frequency for the step up transformer is 50Khz
Is video ko hindi me banaye
Okay
