“…Several kinds of high power radiation sources have been created. There currently appears to be a strong inclination towards compact and autonomous sources of high power microwaves (HPM) (Cadilhon et al, 2010;Pécastaing et al, 2009). The systems discussed here always consist of an electrical high pulsed power generator combined with an antenna.…”

“…The generator coaxial output requires a compact dielectric having a cylindrical shape, such as the one presented in Figure 1. This geometry is very common for insulators placed at the input or output of pulsed power generators [8][9][10][11][12][13]. At the same time, this particular shape of dielectric has certain features that have to be observed in order to avoid flashover, which makes the published formulas for simple geometries not applicable for calculating the surface breakdown voltage.…”

This paper investigates the electric breakdown along the surface of a cylindrical dielectric, part of a coaxial transmission line. The particular geometry of the insulator is very common, as it is used at the input or output of most high-power, high voltage generators. The streamer propagation criterion is used to calculate the flashover voltage. Studies of the dependence of the flashover voltage on the distance between the electrodes obtained in tests with DC voltage and also by applying voltage impulses with different durations and rise-times are reported. The highest difference between the estimated values and the experimental data is less than 15%, which proves the applicability of the criterion for determining the surface breakdown voltage within the geometry under study. In particular, the results of these studies are used in the design of a compact 0.5 MV pulsed power system currently under development.

“…One is the Tesla transformer, for example, the Sinus-type ultra-wideband system developed by the Institute of High Current Electronics (HCEI) [9][10][11][12], and RADAN series developed at the Institute of Electrophysics [13]. e other is to use the Marx generator to generate high-voltage pulse for driving bipolar pulse [14][15][16][17]. According to the published literature, the volume and weight of 10 GW bipolar pulse generators are relatively large, which limits the further application of the system.…”

A compact high-power ultra-wideband bipolar pulse generator based on a modified Marx circuit is designed, which is mainly composed of a primary power supply, Marx generator, sharpening and cutoff subnanosecond spark gap switches, and coaxial transmission lines. The Marx generator with modified circuit structure has thirty-two stages and is composed of eight disk-like modules. Each module consists of four capacitors, two spark gap switches, four charging inductors, and a mechanical support. To simplify the design of the charging structure and reduce the number of switches, four groups of inductors are used to charge the capacitors of the Marx generator, two of which are used for positive voltage charging and the other two for negative voltage charging. When the capacitor of each stage is charged to 35 kV, the maximum output peak voltage can reach 1 MV when the Marx generator is open circuit. The high-voltage pulse generated by the Marx generator charges the transmission line and forms a bipolar pulse through sharpening and cutoff switches. All transmission lines used for bipolar pulse generation have an impedance of 10 Ω. When the 950 kV pulse voltage generated by the Marx generator is fed into the transmission line, the bipolar pulse peak voltage can reach 390 kV, the center frequency of the pulse is about 400 MHz, and the output peak power is about 15.2 GW.
