#98959 - my doubt is Responding to: ???'s previous message |
Dear Prahlad,
one thing that i dont understand is why are we lifting the threshhold of the the zero cross by lifting the Vref up to 1.36 volts. as you are stepping down the voltage, doing so will lift the actual crossing detection point furhter up by factor of 10. Abhishek |
