A SMART OVERVOLTAGE PROTECTION CIRCUIT AND A METHOD THEREOF

摘要

The present invention provides a smart overvoltage protection circuit (100) comprising an AC power line (110), at least one switch (120) connected to the AC power line (110) and an overvoltage detection module (130) connected to the at least one switch (120) and the AC power 0 line (110). Further, the overvoltage detection module (130) comprises a voltage divider (210), a sensing circuitry (220) and a control module (230) such that the voltage divider (210) is configured to divide voltage of the AC power line (110) to obtain divided voltage, the sensing circuitry (220) is configured to generate a first output signal and a second output signal 5 and the control module (230) is configured to receive the first output signal and the second output signal and turn the at least one switch (120) from a closed position to an open position in response to receiving the first output signal.
