Voltage surge electronic control circuit and method
Abstract
Abstract AN ELECTRONIC CIRCUIT AND METHOD FOR PROVIDING AN OUTPUT SIGNAL IN RESPONSE TO A VOLTAGE SURGE IN AN ELECTROEROSION MACHINING CIRCUIT OR THE LIKE. THE ELECTRONIC CIRCUIT COMPRISES A RESISTOR CONNECTED ACROSS THE GAP OF AN ELECTROEROSION MACHINING CIRCUIT BETWEEN A WORKPIECE AND TOOL, A FILTER CIRCUIT CONNECTED ACROSS THE RESISTOR FOR FILTERING EXTRANEOUS SIGNALS FROM SENSED VOLTAGE SURGE SIGNALS AND PROVIDING A SUBSTANTIALLY UNCHANGED VOLTAGE SURGE OUTPUT SIGNAL SUBSTANTIALLY IMMEDIATELY ON OCCURRENCE OF A VOLTAGE SURGE, AN OUTPUT AMPLIFIER CIRCUIT FOR PROVIDING A SUBSTANTIAL OUTPUT SIGNAL ON RECEIPT OF A VOLTAGE SURGE SIGNAL OF A PREDETERMINED MAGNITUDE AND AN ALTERNATING SIGNAL COUPLING CIRCUIT CONNECTED BETWEEN THE FILTER CIRCUIT AND OUTPUT AMPLIFIER CIRCUIT FOR COUPLING FILTERED VOLTAGE SURGE SIGNALS TO THE OUTPUT AMPLIFIER CIRCUIT WITHOUT EXTRANEOUS VOLTAGE SIGNALS.
