High voltage/current pulse generator using spark gaps

摘要

A high voltage/high current electric pulse generator. Spark gap switches (E1, E2, E3) having a trigger electrode are connected to a trigger control circuit (CD). Switch (E1) is connected between the outer conductor of cable (C2) and an inner conductor of cable (C1). Switch (E2) is connected between the outer conductor of cable (C3) and the inner conductor of cable (C2). Switch (E3) is connected between output terminal (S) and the internal conductor of coaxial cable (C3). The outer conductor of cable (C1) is connected to ground and voltage source (SHT) is connected to internal conductors of the cables. The source charges cables (C1, C2, C3) in parallel when switches (E1, E2, E3) are off. A first ballast resistor (r) is connected between the first electrode and the trigger electrode. Load resistor (R6) is connected between the output terminal(S) and the external conductor of cable (C3). Resistor (R5) is connected between the outer conductor of cable (C 3) and the outer conductor of cable (C2). Resistor (R4) is connected between the outer conductor of cable (C2) and ground. Resistor (R3) is connected between the inner conductor of cable (C3) and the inner conductor of cable (C2). Resistor (R2) is connected between the inner conductor of cable (C2) and the inner conductor of cable (C1). Resistor (R1) is connected between the inner conductor of cable (C1) and voltage source (SHT). Load resistors (R2, R3) are connected between the internal conductors of the coaxial cables.
