Abstract
An arc discharge protection apparatus operating in a current detection mode aims to prevent arc discharge caused by abnormal conditions in a high voltage output zone. The arc discharge protection apparatus has a current signal sampling unit to receive an arc discharge current signal generated in the high voltage output zone, an interpretation unit to provide a determination level to sift out an abnormal current frequency signal, a commutation unit to receive and rectify the abnormal current frequency signal and output an arc DC signal, and a touch control unit driven by the arc DC signal to output a trigger signal to stop operation of the high voltage output zone. Thereby sparking or burning caused by heat accumulation of the peripheral elements resulting from the arc discharge can be prevented.
