Zero Crossing Detector using Operational Amplifier(Op-Amp) in HINDI

Zero Crossing detector Zero crossing detector is basic comparator circuit with zero reference voltage It is used to detect sinewave transition from positive to negative, when input crosses from zero voltage condition. That means it use to find the wave’s zero voltage point It is a sine wave to square wave convertor It is used to control AC switch Types of zero crossing detector Inverting zero crossing detector Non- Inverting zero crossing detector Inverting Zero crossing detector Signal is applied at inverting terminal Zero Reference voltage is applied at non inverting terminal Non-Inverting Zero crossing detector Signal is applied at non-inverting terminal Zero Reference voltage is applied at inverting terminal Applications As frequency counter Switching purposes in Power electronics As Phase meter
