High-power microwaves are generated using high voltage (HV) pulses, which are generated using a Marx generator connected to a peaking stage. The output of the peaking stage is the input to the half transverse electromagnetic (HTEM) horn-type antenna. This paper discusses the effect of isolation distance between HV tapered arm and the grounded reflector on the variation of characteristic impedance and gain with respect to the length, flair angle, and tapering angle of the antenna. This paper also discusses the radiation loss on the side and back of antenna. An experiment has been described using an available Marx generator and HTEM antenna. Using the experimental and simulation results, the optimal design parameters of antenna are obtained.

“…However, the sensors are rarely mentioned in the published HEMP simulator studies. Some researchers uses specially designed voltage sensors for specific nanosecond pulse measurements [5,7,8]. However, practitioners have struggled with the challenge of calibrating ns pulse sensors, which is often conducted by comparing with available commercial probes, such as P6015 and P6139A [9][10][11], or standard attenuators [12][13][14] at low-intensity pulses.…”

“…It is challenging to directly generate high-amplitude pulse voltages with a semiconductor-based circuit. Considering the operating voltage and current requirements of switches in HEMP simulators, gas spark gaps are adopted in some nanosecond pulse generators [5,6,8,[17][18][19][20][21]. The FEMP-2000 [5] and HEREMP [6] from Centre d'Etudes de Gramat, France, use three spark gaps in series and control the switch operating voltage by adjusting the SF 6 gas pressure.…”

Due to the lack of a standard nanosecond high-voltage pulse generator for sensor calibration, a high-stability nanosecond high-voltage pulse test system was developed in terms of circuit analysis, structural design, and performance test. By establishing the equivalent circuit model of the nanosecond pulse generator, the circuit component parameters of the five-stage Marx loop and the one-stage compression steepening unit were simulated. The influence of the action performance of the steepening gap on the characteristics of output nanosecond pulse was analyzed. The nanosecond pulse test system was established through the structural design of the nanosecond pulse-generating circuit, the development of a high-performance corona-stabilized switch, and the measurement of a fast-response resistance divider made of metal oxide thin-film resistors. The nanosecond pulse test system has the capability to output a double exponential nanosecond pulse voltages in the amplitude range of 10–60 kV with a rise time of 2.3 ± 0.5 ns and a half-peak time of 23 ± 5 ns. In addition, the output pulse voltage has a high consistency and stability in the full amplitude range. The maximum relative standard deviation of the peak value is 1.517%, and the relative standard uncertainty is less than 5‰.

Pulse forming networks and Marx generators are the classical rectangular waveform pulse generators (PGs). They are inflexible and their capacitors must be fully charged to the required voltage from 0V before delivering each high-voltage (HV) pulse. They are only able to generate unipolar pulses; if bipolar pulses are sought another generator fed from a negative supply voltage is added. Recently, several power electronics based PGs have been proposed. This paper presents an HV power electronics based PG, which is based on Half-Bridge Modular Multilevel Converter (HB-MMC) sub-modules (SMs) charged sequentially in a voltage boost mode. Each SM capacitor and main switch form a boost converter with the charging input supply and inductor. As a result, all SM capacitors are charged to a voltage greater than the input. During the discharging process the SM capacitors are connected in series, producing a rectangular HV pulse across the load. The proposed charging method allows a reduction in the converter footprint in comparison with recently proposed MMC sequentially charged PG topologies. Although only rectangular pulse waveforms are sought in this paper, a SM capacitor voltage balance method allows multilevel pulse generation. The viability of the proposed converter is confirmed by MATLAB/Simulink simulation and scaled-down experimentation.ReView by River Valley Technologies IET Power Electronics 2018/12/10 16:12:53 IET Review Copy Only 2This article has been accepted for publication in a future issue of this journal, but has not been fully edited.
