Abstract:
A phase detecting device includes a power input unit that receives an AC voltage; a phase detector that detects zero-crossing points of the AC voltage, and outputs a phase detecting signal when the zero-crossing points of the AC voltage are detected; and a power switch that selectively cuts off a flow of AC into the power input unit in response to a mode control signal.
