Abstract
An electric shock protection device is provided, including a voltage input unit, a rectifier unit, a determine unit, an output control unit and a switch unit. The voltage input unit receives an AC voltage, and the rectifier unit rectifies the AC voltage to time-varying DC voltage. The determining unit determines whether the time-varying DC voltage is less than or greater than the preset voltage and selectively chooses an output control signal to determine whether there is an external receptor connected in series with the input power. The output control unit is driven by the control signal to make the switch unit control whether the time-varying DC voltage is provided to the electrical load, and to sustain or interrupt the conductive circuit loop. Accordingly, the receptor can be avoided from being subjected to an electric shock from high AC voltage.
