    Sir, aap jo batate hai, bilkul barabar samaj me aa raha hai. Lekin samjane ke liye jo method batate hai uske piche ka logic kya hota hai wo bhi please bataiye.

    • @vccground-hindi
      @vccground-hindi  9 месяцев назад +7

      Feedback aane se se pehle optocoupler ki pin 3 aur 4 ke beech resistance high hoti hai. Isliye LED dim jalti hai. Jaise hi feedback on hota hai, 3 aur 4 number pin ki resistance low ho jati hai aur isi liye LED full bright ho jati hai...bas yahi logic hai dost ❤️👍

      Sir 5v supply output pr diya gya hai.
      Led Optocoupler ke pin 2,4 pr connect hai jo transistor ke emmiter aur collector hai pin hai.
      Sir Question yah hai ki transistors ke Base pr Beena trigger kiye bina (current) LED on kaise ho gya.
      Kyoki emmiter aur collector ke beech me base hota hai.

    • @sanjayyadav2263
      @sanjayyadav2263 9 месяцев назад

      Jab tk base pr koi current dege nhi to transistor switching ki tarah kaam kaise karega.
      Please sir yah concept samjha dijiye.

      @@sanjayyadav2263 yahan sirf optocoupler hi nahi laga hai dost. Circuit me dusre components bhi Lage hue hain...unme se kisi component se kuch leakage current aa raha hai, jiski wajah se bina feedback bhi LED dim on ho raha hai ❤️👍

      2 या 4 मॉस्फेट/ट्रांज़िस्टर वाले सर्किट पर आगे की वीडियो में बताऊंगा दोस्त। अभी ये सब बताने से किसी को कुछ समझ नही आएगा। इसलिए धीरे धीरे उस तरफ ही बढ़ रहे हैं हम। 5-24 मॉड्यूल में जो 8A का मॉस्फेट लगा था वो प्राइमरी साइड में स्विचिंग् करता है। और एक स्टेप डाउन ट्रांसफॉर्मर में सेकंडरी साइड का करंट हमेशा प्राइमरी से कई गुना अधिक होता है। इसलिए 8A मॉस्फेट से प्राइमरी में अधिकतम 8A करंट बहेगा, परंतु सेकंडरी में वो बढ़ कर 30A से अधिक हो जाएगा। यह सब एक वीडियो के माध्यम से समझाऊंगा आपको ❤️👍

    2 और अगर O/p 5v के बदले कम देती है तब
    3 और O/p 5v ke बदले 7v तक बढ़ाने है अथवा 5v के बदले 3.3 कैसे करेंगे
    4 और dth वाला smps से शॉर्ट किलर बनाए तो ये smps डेमेज हो सकता है

    Sir can u make video about maltiple output power supply like 3.3v 5v 12v
    In one pcb . How to divede the voltage after chopper transformer or shotkey diode to get multiple voltage

    • @vccground-hindi

      3.3v is made using a linear regulator while 5v, 9v, 12v or higher are generated using different secondary windings.❤️👍

      Jo optocoupler AC line se juda hai, wo AC line sense karne ke liye hai. SMPS me ek optocoupler aur hoga jo output voltage se juda hoga aur usko regulate karta hoga dost ❤️👍
