Why we use 2 opto coupler for zero crossing detection. Is there is no bridge for rectification . Can you explain the need for 2 opto coupler. I have seen the video of zero crossing detection using bridge rectifier and a transistor with micro controller
Sir ji namaste. Sir aapke video se bahut se pcb ko repair kar pa rahe hai aur me v bahut details se fault aur solution ko batate hai. Thank you 🙏🙏. But sir aisa kabhi kabhi hota ki spare parts same number ke available nahi hote mere nearest market. Lg ke inverter split AC me 8550 transistor ka equivalent bataya aur working me motor ho gayi. But sir aapka number agar dete to bahut meharbani hogi. Kyoki kuch problem thode different types ke hone ke karan aapke thodi hints ke liye aapka WhatsApp number chahiye sir ji. Thank you 🙏🙏🙏
