A Moderate Energy, High Repetition Rate Marx Generator System for Pulse Charging Wide Band Antenna Structures

An ultra compact Marx generator system is fabricated for driving a wideband antenna structure with high repetition rates. The generator is designed to deliver 100 J per pulse, with an erected voltage of 640 kV. The generator employs an inductive element charging topology, which allows the 16 stages to be rapidly charged to a maximum voltage of 40 kV. The generator also integrates a 10 kW rapid capacitor charging power supply, which compactly mates to the end of the Marx generator. Design considerations are presented, as well as experimental results.
