High power pulse generator having a substantially quadrangular shape with an adjustable slope

High-power pulse generator (1) comprising:

• a first series of power modules, called standard modules (3s), each comprising a switch, called standard switch (6s), provided with a trigger electrode (9s), positioned in series with at least one capacitor (4s) with a first capacitance value, said standard modules being designed to produce a pulse at a first frequency when said switch is closed;
• a second series of power modules, called modified modules (3m), each comprising a switch, called modified switch (6m), provided with a trigger electrode (9m), positioned in series with at least one capacitor (4m) with a second capacitance value, said modified modules being designed to produce a pulse at a second frequency when said switch is closed, said second frequency being substantially three times that of the first frequency;
• a central core comprising a magnetic core that comprises at least one ferromagnetic ring (7) designed to add the pulses produced by said standard (3s) and modified (3m) modules in a load (8) concentric to said ring(s) and to obtain a substantially quadrangular shaped resulting pulse comprising a rising edge, a plateau and a falling edge;
• a trigger device (13) designed to control said standard and modified switches (6s;
• 6m) by a trigger signal applied to their trigger electrode (9s;
• 9m),
• said generator (1) being characterised in that said trigger signal is applied to said switches through a trigger impedance (10m;
• 10s) connected to the trigger electrode of the switch, with the trigger impedance of said modified switches, called modified impedance (10m), being distinct from the trigger impedance of said standard switches, called standard impedance (10s), and in that a slope of the pulse plateau depends on the difference between the value of said standard impedance and that of said modified impedance.
