Abstract: A method for detecting sudden-up and sudden-down of voltage includes generating reference sine signal with the same phase and fixed amplitude as voltage signal of power supply, rectifying power supply voltage signal and reference sine signal then comparing rectified power supply voltage signal with rectified reference sine signal for obtaining detection result to present whether voltage is sudden-up or sudden-down.
