Sir aap ke samjhane ka andaz anokha hai jaldi samajh me ata hai.sir pl V12 car amplifier ka power supply ko samjhaye.
12V car ki supply me kya samjhna hai aapko ?
@@vccground-hindi 12 volt dene ke baad voltage drop hota hai bohat kam voltage ata hai 24 volt nahi ban rahe hai TL 494 ic maine change karke dekh liya 4 transistor aur 2 mosfet bhi change karke dekh liya phir bhi short circuit ho raha hai mosfet bohat garam aa rahe hai.aur teeno diode. Zener bhi change kardiya. .hal bataye......?
Dear sir,
Normal power supply explain verey nice but new topic in same explain FFC Power Supply video with troubleshoot & IC Replacement IC or module.
Yes, we will come to that also brother ❤️👍
Led tv PFC supply pe vodio banwaye
Thank you sir you are very nice ☺️
Most welcome brother ❤️👍
Better work for electronic engineers

I love the RICE explanation re volt-drop across the resistor 😂
Thanks brother ❤️👍
Thanks sir❤❤❤❤
All the best brother ❤️👍
Nice

Sir ji apka samjhane ka tarika bahut hi achha hai bahut bahut shukriya.sir ji ic per volt nahi aa rahi hai swiching transister aur other component bhi ok hai hir bhi switching nahi ho rahi hai pleàse me.
Jawab ke liye mera video number 80 dekh lo dost, usme yahi sab bataya hua hai maine ❤️👍
I am having duel o/p 5-5-0-0-12V SMPS of which 12v o/p zero will you pl. suggest which video I should refer.
Check output section of 12V supply...there must be some open aur short circuit scenerio...
SIR PLEASE EXPLAIN PFC CIRCUIT.
ZERO CROSSING DETECTOR
Dost thoda samay dijiye. Uss par bhi video banayenge 👍
Respected Sir, very well explain and knowledgeful. If you don't mind, when you free and if possible, strongly request for explain the solar inverter without Battery. I will be ready to pay the cost if any because I am facing very problem during repairing. Because I am new trainee and only get knowledge source from you. With best regards.
Give me some time brother. I take every topic step by step 🙏
@@vccground-hindi OK. Thank you Sir.
Respected sir, ek bar aap axiom power supply ke circuit par bhi video bana dijiye to bahut badi kripa hogi❤👏
Banaunga dost bas thoda samay dijiye 🙏
@@vccground-hindi Thanku sir, hamen intejar rahega 👏
Aap jis multimiter ka istemaal karte hai wo mujhe bhi chahiye. Pankaj Somra,Chirawa.
Uske liye aap mujhe 9310248748 par whatsapp message bhej kar mangwa sakte ho dost ❤️👍
Sir please timing capacitor and timing resistor general calculation explain
Ok dost ❤️👍
Pranam sir ji ❤sir ji circuit ka feedback protection samazate hue Maine socha ki is circuit mein aane wali sambhavya kharabiya kuch jada nahi hogi, mere khayal se
1 IC ka 5v continue chalane se open hoga
2 regular up and down frequency par kam kaprne par IC ke inbuilt osc transistor open or short hoge
3 by chance heavy current flow hone par current controller open or short hoga
4 regular frequency par kam kaprne Wale buffer transistor our out put transistor short or open hoge
Baki sab feedback protection ki vajahase kharab ho ne ke bahut kam chances hai , krupaya meri soch ko suzav dijiyega dhanyawad sir ji pranam ❤❤❤❤
Sahi keh rahe ho dost. Kuch problem aur bhi aati hai, wo aane wale videos me bataunga aapko 👍
Sir ji. Dead time control pin par Voltage divider formula ke dwara bhi voltage prapti Karen sakte hain.
Bilkul dost ❤️👍
Hi sir
Sir aapke paas jo HTC DM-85T multimeter hai vahi same mere paas bhi hai to hum usme smps ke primary side jo live voltage hote hai uski pwm ic ki frequency magermant kar sakte hai ya nahi ?
Kar sakte ho dost, par ye meter high voltage par frequency sahi nahi batata hai. Switching IC ki pin par hi sahi batayega ❤️👍
Dear sir
Mera 1 sawal bahot dino se
esi supply pe h
Ki output pe fek 14 volt aate h par lod dalte hi 5 volt ho jate h
Please es topic pe video banwaye bahot help hogi
❤❤❤❤❤
IC kon si lagi hai usme ?
Hello sar ji rlc cricut me kitna cold testing value Ani chaye sar output me kitna reading Ani chaye sar
Jo reading video me meter me aa rahi hai dost ❤️👍
سر آپ کے وڈیو بہت معلوماتی ہوتے ہیں pwm کے بعد mppt سپلائی کی معلومات بہیں دیں کہ وہ کیوں اور کس طرحہ pwm سے بہتر ہے اور کس طرح اس کو مزید بہتر کر سکتے ہیں
ٹھیک ہے بھائی، نوٹ کیا۔
Hi sir I have a limited solar setup that is producing almost 1 kilowatt. I have a Chinese 2 kilowatt square wave inverter. I want to run an electric iron on it. Change the electric iron is 1000 watt but my solar output is 1000 watt. In this 1000 watt almost 200 Watts are used by my all load. So it's been times I have almost 6 to 800 Watts left behind. Change the electric iron is 1000 watt I want to modify the inverter so that its output remains of for 60 to 70% of the time. That is I want to reduce its duty cycle. The inverter is using tl494 at its output and input drive circuits. I have tried adjusting rtct but it seems that the rtct is also connected to some other part of the circuit as a feedback and I cannot adjust the duty cycle I have checked on a oscilloscope it's still the 3% dead time. Do you think that if we are able to adjust the dead time to 50% or more or 60% we can reduce the output power and hence I can accommodate the electric iron.
Please if you can guide me on this assumption .. and help me identify how I can control the dead time.
Yes, you can increase the voltage on dead time control pin by increasing the value of the resistor connected between this pin and ground. This way dead time will increase and consequently duty cycle will drop ❤️👍
Pl. Tell inverter welding machine
Will explain that soon brother ❤️👍
Sir ji jab IC Ki dono drive plus me volteg ka anter hone par yah problum kaise sahi kare axiom charger me 3525ic Ki drive pin 11our14 ki voltage me anter mila h jab ki swhiching transistor nikalne k bad bhi problem nahi hati
Usse charger ki output me kya problem aati hai aapko ?
what is totempole? is it switching data between the transistors pins pls explain sir
Totem pole is a two transistor (NPN+PNP) push-pull setup that are connected in series with each other with their base joined together to run from a single drive signal. When the input signal is low, PNP transistor will conduct. And when the signal is high, the NPN will conduct. Hope its clear now...❤️👍
Sir mayray pass ADP-48CR AA number ke supply ha iss kay baray main malomaat dain thank
Dost agar ye supply mere paas aayegi to jaroor uss par bhi video bana dunga ❤️👍
Pranam sir ji, sir ji mera sawal hai SMPS ke aage out put me hajaro part hoge agar koi chotasa part short ho jayega toh current flow badh jayega our DTC controller shut down karwadennga fraction of second fir chalu honga vah to current mager hi nahi karne denga prob lagatehi band chalu hota rahenga hame pata kaise chalenga currents konsa section kha raha hai Power ke bina toh trouble shooting sambhav nahi krupaya samadhan kijiye guruwaryaa ❤pranam dhanyawad sir ji
Thoda intezaar karo dost. Har section ke fault ki baat karenge agle videos me ❤️👍
@@vccground-hindi pranam sir ji,thik hai sir ji
Aap Circuit me or bhi check karke bataye. Jese ki transistor, transformer me kitne voltas ate hai.
Transistor and transformer kese check kar sakte hai. Khrab hai ki nahi ?
Thoda samay dijiye dost. Sab cheezon ki baat karenge ❤️👍
Dead time overlapping के बचाओ के लिए भी जरूरी होगा ? ताकि दोनों ट्रांजिस्टर क्रास न कर पाये ।
बिल्कुल सही कहा आपने ❤️👍
Sir aap my mujay reply nai kia 1 request mn my bki thi plz
Dost mujhe aapka battery charger wala comment yaad hai. Samay nahi mil pa Raha hai. Thoda ruko, bata dunga 🙏
