Circuit arrangements for the damping of excess voltages in shock potential generators

Claim 1

AN IMPULSE GENERATOR COMPRISING A PLURALITY OF VERTICALLY SUPERIMPOSED STAGES CONNECTED IN CASCADE, EACH STAGE COMPRISING IN COMBINATION, A DAMPING RESISTOR, AN IMPULSE CAPACITOR AND A SPARK GAP IN SERIES CONNECTION AND HAVING INHERENT INDUCTANCE, AN ADDITIONAL RESISTOR BRIDGING SAID SPARK GAP AND SAID DAMPING RESISTOR, AN ELECTRICAL CONDUCTOR CONNECTED INTERMEDIATE SAID CAPACITOR AND SAID SPARK GAP AND LEADING TO A TERMINAL FOR CONNECTION TO ONE POLE OF A DIRECT CURRENT VOLTAGE SOURCE, DIRECTLY IN THE CASE OF THE FIRST STAGE AND VIA A CHARGING RESISTOR IN THE CASE OF SUBSEQUENT STAGES, AN ELECTRICAL CONDUCTOR LEADING FROM THE DAMPING RESISTOR OF THE FIRST STAGE TO THE OTHER POLE OF SAID DIRECT CURRENT VOLTAGE SOURCE, SAID IMPULSE GENERATOR HAVING STRAY CAPACITANCE BETWEEN STAGES FORMING WITH SAID INHERENT INDUCTANCE A SERIES OSCILLATION CIRCUIT CAPABLE OF BUILDING UP EXCESS TRANSIENT VOLTAGES OF CONSIDERABLE MAGNITUDE BETWEEN SAID SUPERIMPOSED STAGES, AND ADDITIONAL CAPACITANCE PROVIDED IN PARALLEL WITH SAID STRAY CAPACITANCE TO REDUCE SAID EXCESS VOLTAGES.
