Special Issue Information

Dear Colleagues,

Pulsed power technology is one of the most promising and rapidly growing research areas in applied physics. Pulsed power technology involves multidisciplinary research covering energy, materials, environment, defense, plasma medicine, and agriculture. High-power electromagnetic pulse power sources can be used in fundamental research projects such as inertial thermonuclear fusion, the production of high-energy electron beams, high-power microwaves, excimer lasers, rays and neutron pulses. Pulsed power generators for gas discharge, water discharge, and electromagnetic field generation have promising applications in material surface treatment, waste purification, water treatment, food processing, and device sterilization.

The development of pulsed power technology focuses on two aspects. On the one hand, the search for methods to obtain record high pulse power and the development of devices to achieve higher pulse voltages and currents is a constant challenge in the field of pulsed power technology. On the other hand, the widespread use of pulsed power supplies in industry continues to provide new challenges and future development opportunities for pulsed power technology research in terms of pulse repetition frequency, average power, compactness, reliability and lifetime.

With this Special Issue, we would like to draw special attention to new ideas that can best support the technological advancement and application development of pulsed power. We welcome both traditional and non-traditional interdisciplinary solutions and also encourage the optimization of existing pulsed power technologies for enhancement and application expansion. This Issue is open, but not limited, to contributions in the following focus areas:

  • High-peak power pulse generators;
  • Spanning high-power broadband electromagnetic sources;
  • Nanosecond pulse generators;
  • High-power switching and high-repetition frequency switching technology;
  • High electromagnetic energy density storage technology;
  • Pulsed electrical insulation and breakdown;
  • Explosive pulsed power techniques;
  • Electromagnetic measurement techniques, intense particle beams and the associated diagnostics;
  • Pulsed plasma applications in agriculture, food, health and biomedicine.

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‰. Full article

In this paper, the design of a self-developed EMP simulator with a 5 m height and an inverted conducting mono-cone antenna with a cone half-angle of 32° is introduced. The experimental region of the simulator is a circular area of 25 m in diameter around the cone vertex. Two feeding modes, feed-in over the ground and feed-in under the ground, are realized by two different high-voltage pulse sources. It can be concluded through radiation field testing that the radiation field waveform generated by the simulator has a rise time of 2–3 ns and a half-width of about 25 ns, meeting the specifications of the EMP experimental waveform in the IEC61000-2-9 standard. Meanwhile, the differences between the engineering implementation of the simulator and its ideal structure during the design process can lead to some distortion issues in the antenna radiation characteristics and the electromagnetic radiation field it generates. The radiation field waveform and the distribution of the EMP field generated by the simulator under different feeding methods, antenna wire quantities, antenna end processing methods, and different antenna resistive loading were studied, and the changes in the radiation field waveform and field distribution with different angles and distances of the monitoring point were analyzed. Based on the measurement results, the radiation characteristics of the antenna and the factors that affect the waveform of the field were studied and analyzed. Through the aforementioned work, a comprehensive understanding of the performance, radiation characteristics, and engineering factors affecting the electromagnetic environment generated by the simulator has been obtained. On this basis, the parameters of the antenna wire quantity, antenna end processing method, and test point position of the designed simulator were reconfirmed and optimized. In summary, this work has important reference significance for mastering the development technology of such simulators, understanding their antenna radiation characteristics, and conducting EMP-related assessments and effect experiments in the future.

Traditional thermal sterilization technology is easy to implement and safe, but it will destroy food nutrition and change food taste. Therefore, people began to turn their attention to non-thermal sterilization. High-voltage pulsed electric field sterilization technology is one of them; it has attracted much attention because of its high efficiency and little damage to food. Different types of loads will cause serious trailing of the pulse falling edge. In view of this situation, this paper proposes a new topology circuit that combines a solid-state switch with a half-bridge Marx generator. It can be used for high-voltage pulsed electric field sterilization. By improving the structure of the classical Marx circuit, the high-voltage pulse power supply of the new topology circuit has the characteristics of steep rising edge and short falling edge delay; does not require isolation inductance or isolation resistance, which solves the isolation problem between the DC charging power supply and the high-voltage terminal; and has a good voltage-clamping function and load adaptability. The working process of the topology circuit under resistive, capacitive and inductive loads and the voltage clamping effect when the solid-state switch does not work properly in the discharge process are analyzed in detail. The power supply is composed of an adjustable DC power supply, five-stage half-bridge Marx generator and control protection circuit. A field programmable gate array (FPGA) is used as the controller to generate control signals, and optical fiber isolation is used to provide control signals for the main loop. The power supply can output a high-voltage square wave pulse with a voltage amplitude of 10 kV, maximum pulse number of 1000 per second, maximum pulse width of 20 μs, pulse rise time of smaller than 300 ns and short pulse drop time, and the repeated voltage amplitude, frequency and pulse width are adjustable, which can meet the requirements of a high-voltage pulse sterilization experiment.
