- Hello friendz i will back with a new video in which i make a transformerless Powersupply it means that we are just going more far away from last video
As in our last video we will make a DC power supply using transformer,It also working fine but, How if we remove that Transformer and again make Same DC supply ☺😊😀 Sound like Good
So in this video i am just going to remove that transformer and transformerless supply
Hope you like it👍👍👍

What is Transformer?
A transformer is used to lower the mains voltage, and also to limit the current. In this power supply, we use a capacitor and a resistor, that together form an impedance that lowers the current from the mains. The voltage is set by a bridge rectifier that includes two zener diodes that set the voltage to a desired value.

Terima kasih sahabat/thanks.. Atas inspirasi dari anda dan sebagai pelajaran untuk saya selaku pemula. Salam dan Horasss dari Nort Sumatera Utara Indonesia
Very good information
Very Good, I like it. Thank you.
Thanks a lot. Got some Qs:
1. What do I need to change to run it on 110v AC (actually it's around 127v)
2. How do you make it variable? for say 3v, 5v, 9v, and 12v ?
I recommend people add some protection like a fuse before the circuit on one of the wires(lines).
Use 105 j in parallel to 1 Mega ohm 1/4 W, use a bridge rectifier IC or a bridge rectifier using 4 IN 4007 diodes, use filter capacitor 1000 microfarad 50 V, use a regulator IC as per your need(7812,7809,7805 for 12 V/09 V/05 V dc respectively....as per your need).....donot forget to attach a heat sink to the IC.....avoid using a zener...in case you use donot use zener below 1 W......use a very low value 2 W fusible resistance for protecting the circuit against ac spikes....keep the entire thing within a plastic/pvc/MDF box with ventillations.....connect the phase(live) with the open end of the pf capacitor otherwise current shock at the dc output is 100% guaranteed.....to avoid mistake,use a 3 pin plug such that live and neutral remains connected at fixed places.
can we use 16v/25v/35v rated capacitor instead of 50v for 5v output?
what should i use to make an 110v ac to 5v dc adapter?
what will be capacitance and volt of condenser
also where you purchase it
5mm 100 led ke series banana hai jo direct ac pe chalega to usme ye circuit rahega ya alag
Sir main 470uf/16v ka capasitor laga sakta hun kya.
sir yaha pe ham 470/50 v ki jageh koi dusra condenser use kar sakte hai
Can I use this circuit in relay module instead of hi link power supply device?
Bhai 100 led keliye konsa bridge rectifier chahiye pls bhai aur diode konsa aur resistance
Wat u get the outputs is it RMS vol or avg voltage....
*thanks very much* but what's the maximum current that the circuit can support
S.kumar bhai ge u r great person nice tip & trick for technology.........
+Mr. Imran ✔👍😁✅⬆
Nice
Very useful
I have a fan motor controller that when turned on supplying (0+ to 120V) will also be able to drive a 5vdc coil relay for a light. Will this circuit deliver 5vdc no matter the AC voltage say 30-120V?
I always love this
Very nice sir ji
you are great
Sir ji ek 70ya 80 volt dc supply ki video bnaeeeye pls with components name and it's details
Can we use LM7805 instead of 5v zener
Bro 12v zener diodes and 12v 1w zener diodes what difference please replay???
Sir, can i use 1N4001 diode ?
I wanna devoid 12 v dc current 6 in 6. pls suggest what for do this
Hi!! what I need to change for add 110 V in??
What is the current in the output of 5volts DC this circuit will deliver
isme 155j 400volt ka pf laga sakte hai
cap ki konsi side doide ki plus _kis side doide m bhi + - hai pls tell
Can i use a 250v pf
I couldn't get a 400 one
thanks i like the circuit. can please tell if is it works without ac np 440v capacitor and resistance on ac side. please explain if it doesn't works and why.
thank you for good circuit design
pf capacitor konsa h
Is it used for mobile charging
greats tutorial..
what will happen if zener diode will get blow any how?
I could not go to the 680 register and 68 ohm stores. How many volt registers or ohms do I need? I have a non-copolar CL21-250v-225k capacitor 470uf35v.date 4007.Jenna's dat is 12v.How many registers and ohms are needed?
15walt led bulb ke liye. Kaun sa PF lagaen?
ye pixel led ke liye chale ga kya
Sir ye circuit output me kitna Amp current deta hai
Fantastic
thanks a lot bro*
but How is equal to the intensity of output current?
How many amp of power cord is used in this ?
Saya bikin rangkaian seperti skema.... tapi hasilnya output kalau diukur bukan 5-6v tapi 20 v lebih... kira2 kenapa ya....???!! Mau saya coba dengan LED takut putus..., tks
thnx bro i like it
capasitor 105j 250v laga sakta hu kya
Sir, resister kitne watt ka lagana he.
its savety for arduino?
So what is the max ampere for this?
Basically you are using a resistor to step down the voltage and then use a bridge rectifier to convert it to DC. Could you let me know what would the cap 22J do with the resistor in parallel? The efficiency and capability of such a stepdown circuit is low and with load the resistor is bound to become very hot. Not a practical design for commercial use. Is there a better way without using a transformer to stepdown 220v to 5.5v?
can i run NE555 IC with this circuit ?
very good
Can i charge 18650 battery using it with tp4057 charging module so there is no overcharging or heating of battery arrive. What is the amp of this circuit..
Sir 470 ki jagah 620 ohm chalega????
Zo what are variable value ..when I wanne have 127 volt...input to 12 volt or 5 volt......?
good work
Is sa mobile charge kar sata ha. Is ka out put amp kitna ha.
Good work
S.kumar is k amp kitne hain or kia is se mobile charge kar sakte hain
What is the function 22j capacitor
CBB 22
22J/ 400V non polor capacitor nahi mil raha. iska actual maan kitna h
thank you
12v z.diod se 12v dc motor chlega

Ring Neck is there any way to increase output current to 1 to 1.5 amp? in this circuit?
I want to make 5 V mobile charger which requires that much output current.
For above 500 mili amp if transformer is the only solution than why all mobile chargers are so lite?
So there has to be some way to get higher output current without using transformer.
Sir kya is circuit ko 24hours Jala kar rakha Ja sakta hai koi short circuit ki problem to nahi Aayegi ya heating problem
Agar is circuit ko 24 ghante active kiya jaye please reply
whit its that , I can supply an Arduino and a relay? 170ma esp8266 more 300am relay, total 470ma.
Bos klo diodanya lbih besar bisa ga bos
good way of explanation.....well understand by anyone....make some more videos like this using basic concepts...good Job
Aap great ho
kitne wat load ke liye h ye
u shown 470k resistor point5whow to buy it from shop what to say for point 5w resistor
bro kya me 4 volte battery charging kar sakta hun kya plz help me bro plz
pf capacitor konsa h
Tanya bosss itu yg warna e merah yg d pararel ma R nama nya apa n ukuranya berapa
Very good........
Isme shock lagta he ki nai bhai kyunki transformer use nahi Kiya he so
good
I want to power a mini electric skimmer (fish filter) that works with 240v and has 5 watts output.my thinking is this electric machine to be portable ,so i want to power it with a power bank that gives 5v .Is this stupid think,or possible to do? If so what should i buy to do that?
Well, why not take the worlds most dangerous circuit and add water? (Er: seriously, just "no").
Please tell me 3.7v to 60v DC to DC 300ma possible ?
Hi Kumar, Thanks for the video, it is really helpful. I want to know that how we can make transformerless power supply for DC 12V
Use 12V zener diode
Where did get pfWhat will be use instead of pf
how much power it consume?
12v keliye kay Kay use karna padega
What if zener diode is not used?
very details i'am very like
Jos lah
105 k non polar capacitor chal jayega
This output is 5v. If l want 12v what l have to do sir.so also cap you have showened before,those are not use. Why sir.
Bisa untuk cas batrai pb gk
How can connect BT136 AC switiching transistor on transformerles power supply????
Sir when i connect the ac220v in inverted position (phase-neutral), i found my electric tester lighting on the output. Why? Am i bound to connect the phase wire of 220ac on the x-rated cap side only? Plz reply me sir.
This generally happens if you get within 2m of this circuit .. You become charged and start vibrating.
specification of capacitor?
I like this video
How can i make a dc to ac converter..or how can i conver 9v dc yo 220 v ac..plz make this video with metirial details, and curcit dayagram
What oke to the vape??
Super
What to do if i need 12V ???
How to increase it's amp. ???
Can i follow the idea bro?
