Patent ID: 6940234

Claim:
An arc discharge protection device for eliminating an arc discharge effect produced by an abnormal phenomena in a high-voltage output area having a power supply unit for supplying electric power, a control unit for providing a voltage distribution signal, a driving unit for receiving said power supply and voltage distribution signal, a step-up unit for receiving said voltage after the conversion and converting said voltage into a high voltage, and a load with a high-voltage output coupled to said step-up unit, comprising: a voltage conversion unit, for receiving a high-voltage arc discharge signal released from said high-voltage output area and converting said high-voltage arc discharge signal into a low-voltage arc discharge signal; a filter unit, for receiving said low-voltage arc discharge signal of said voltage conversion unit and determining a potential and filtering an abnormal frequency signal; a rectify unit, for receiving said abnormal frequency signal of said filter unit, and outputting an arc wave clutter after performing the rectification; a touch control unit, for detecting said arc wave clutter and outputting a trigger signal to stop the operation of one selected from the group of said control unit and said driving unit to prevent said arc discharge effect.
