Another well described video Sir. I was making notes on my printed circuits as you were describing. I never would have understood this circuit without your brilliant teaching. PS, current feedback voltage for say 20A smpsu would be 0.039V (not 0.39V as parallel shunt Rs=0.00195 ohms). FYI, I have a faulty half-bridge smpsu. When I get a moment I will check it out as per your teaching and hopefully will learn more.

Salam Dear Talented brother, i have 3 questions if i may: 1- In the FB section, why having 10K and 220R in the positive side of the voltage divider, why not only 1 resistor ? 2- In the same section, why having in parallel a 33nF capacitor ? 3- most importantly, i do not get what is the output of the 1815 transistors and where do they get it from. Are they transmitting ground or positive voltage ? Many thanks for that excellent course.

@vccground-hindi 2 ай бұрын

1- Because resistors are not available in every required value, hence we use two or more resistors in series or parallel combinations to get that required value. 2- A parallel capacitor is used to avoid sudden change in feedback voltage level. 3- Output of transistors C1815 will be negative as we have connected ground line to the emitter of both transistors through diodes D1 and D2. Hope this clears all your doubts ❤️👍

आपका समझाने का अन्दाज बेमिसाल है हर चीज को बारिकी के साथ समझाने की कोशिश एक अलग ही लगाव/ सोच पैदा कर देता है जिसे भावनाओं से ही समझा जा सकता है । ये विषय जटिल (हमारे लिए) होने के कारण कुछ बॉन्सर से चले जाते है इसके लिए वीडियो को कई कई बार देखना पड़ेगा आगे इसी क्रम में R6,R7 और इन्ही के just बगल मे D 1&2 और C7 दिखाये दिये शायद उनका जिक्र नहीं आया। कृपया अगली वीडियो में थोड़ा प्रकाश डालने की महेरबानी करना जी Iमेरी भूल हो तो क्षमा चाहता हूं - धन्यवाद

शुक्रिया सर। जैसा कि आप ने खुद ही कहा कि ये विषय जटिल है, इसी वजह से मैंने इस सीरीज की पहली या दूसरी वीडियो में ही कहा था कि इसमें मैं बहुत गहराई में न जा कर, सिर्फ उतना ही विस्तार से बताऊंगा जितना इस सप्लाई को रिपेयर करने के लिए आपको जानना जरूरी है। उन्ही कंपोनेंट की बात करूंगा जो इसमें अक्सर खराब होते रहते हैं। मेरी कोशिश यही है कि यह विषय जटिल होने के बावजूद जिस तरह आप सब को आसानी से समझ आ पाये, उसी तरीके से ही बताऊं। अगर एक बार आप समझ गये, उसके बाद हम गहराई में भी उतर पाएंगे, वरना किसी को कुछ समझ नही आएगा, सब ऊपर से ही निकल जायेगा 🙄

@vccground-hindi 2 ай бұрын

1- IC ke andar NPN transistor Lage hain, aur NPN transistor negative supply ko hi switch karta hai. isaliye bahar Wale transistor ko pull up karke negative signal Diya jata hai. 2- output voltage high hone par jab OpAmp ka output high hoga, to wo transistor ko off nahi karta hai, kewal uski duty cycle ko wahi rok deta hai. Switching band nahi hoti hai dost. Ye baat maine video me bhi already batai Hui hai...😊

If you decrease main DC capacitor value, output voltage may drop on full load ❤️👍

Ye C24 ka fayda thikse samaj mai nhi araha Bhai. Agar ye capacitor hatake direct kar denge to kya hoga?

@vccground-hindi Ай бұрын

C24 iss SMPS ka startup capacitor hai jiski wajah se Switch start hoti hai. Agar aap isko hatake direct kar denge to +155v wali line 0V line ke saath direct jud jayegi aur short circuit ho jayega..aur fuse bhi udd jayega dost ...

UC3845 50% डयूटी साईकल पर काम करती है। आप UC3842 या 3843 लगा कर देखो, जो कि 100% डयूटी साईकल पर चलती है और अधिकतर smps में काम करती है 👍
