Special Issue Information

Dear Colleagues,

Pulsed power is marked by the pursuit of high peak power, and enables the achievement of faster, stronger, and extreme electrophysical conditions. Traditional pulsed-power technology usually uses gas switches as its main component for pulse modulation and formation. In recent years, driven by various application requirements, the demand for pulsed-power technology with high repetition rates has become increasingly urgent, and pulsed power has gradually developed towards high repetition, solid state, and miniaturization.

High-power electronics is a technical discipline that utilizes repetition frequency and modulated power supply technology composed of modern semiconductor switches to achieve specific electrophysical effects. With the improvement of semiconductor switching technology (MOSFET, IGBT, GaN, SiC, PCSS), its voltage, current, and power levels have gradually increased. On the other hand, due to the development of the solid-state Marx generator and solid-state LTD technology in recent years. High-power electronics combines power electronics technology with high-voltage pulsed-power technology. This technology has undergone significant growth and development, providing numerous opportunities and challenges for researchers, scientists, engineers, and experts in various disciplines.

Although there is still a gap in knowledge on the peak power level of high-power electronics compared with pulsed power, their peak power and average power are constantly being upgraded. As the vacuum tube computer is replaced with the integrated-circuit-based computer, the future pulsed power of gas-based switches could be replaced with the high-power electronics of solid-based state switches.

High-power electronics power supply systems have the advantages of miniaturization, long life, controllability, and high . There is no doubt that they will find wider application and undergo development in the fields of defense, scientific research, and industry.  

This Special Issue invites authors to submit original research articles, review papers, and technical notes that showcase advancements in pulsed-power technology and high-power electronics, with the goal of fostering interdisciplinary collaboration and facilitating knowledge sharing. The contributions included in this Special Issue will range from fundamental scientific research to practical applications and cover a diverse range of topics, highlighting the broad potential of pulsed-power technology and high-power electronics across multiple domains. The Special Issue aims to provide a platform for researchers, scientists, engineers, and experts to share their latest findings, cutting-edge technologies, and insights on practical applications in the field of pulsed-power technology and high-power electronics.

Currently, pulsed adders are used as pulsed voltage sources maturely. However, their use as pulsed current sources is significantly limited due to circuit impedance and the characteristics of power devices. This paper presents a simple yet effective design for a pulsed current source, incorporating a solid-state Marx pulsed adder as the primary power source and an inductor for energy storage. In the pulsed current source, a Marx pulsed adder produces high voltage to charge the inductor. Then, the stored inductance energy is converted to generate current pulses on the load; the amplitude of the pulsed current is unaffected by the load impedance within a certain range. The pulsed current source can be designed as a standard module, and several modules can form a cascade system for producing current pulses with higher voltage. Finally, a pulsed current source was developed, which can produce adjustable current pulses with high voltage. The design principles, control methods and the effects of the distribution parameters are described. The feasibility of the cascade pulsed power system was validated in experiments. Nine modules were connected to generate pulses of current 10 A on a 15 kΩ resistor. Full article

In solid-state high-voltage pulse generators, switches may be triggered on by fault due to electromagnetic interference, resulting in high through current and breakdown of switches. To generate rectangular high-voltage pulses, this paper proposes a solid-state Marx generator (SSMG) with fast recovery diodes to prevent through current. Only charging currents with the same direction flow through these fast recovery diodes breaks the short-circuit loops in and between stages. A 52-stage SSMG prototype based on the proposed circuit was developed. PSpice simulations and experiments were performed for comparison. It was found that the through current can rise to 250 A without any protection. With 10-μH protection inductors in each state, the through current amplitude drops to 50 A. Under the same condition, there is no continuous through current with the proposed fast recovery diodes. Furthermore, 22-kV repetitive rectangular pulses were also obtained in experiments. This proved that the proposed Marx generator can prevent the through current in power cells. Full article

In this paper, a control method of a full-bridge DC–DC converter for a pulse power supply with controllable charging time based on Active Disturbance Rejection Control (ADRC) is presented. For this application, the scheme objective is to achieve a flexible charging current to adjust the charging time of the pulse power supply. Due to the existence of switching devices in the system, the dynamic characteristics of the control system are complicated; an LADRC (Linear Active Disturbance Rejection Control) controller is constructed to regulate the charging of the converter current so as to improve the flexibility and dynamic performance of high-voltage pulse power supply. LADRC linearizes the extended state observer and links its parameters to the observer bandwidth to simplify the design of ESO. The proportional coefficient or differential coefficient is connected with the bandwidth of the controller to simplify its tuning, simplify the nonlinear function, more parameters, and complicated adjustment of the ADRC in practical application. The inner loop current regulator assembled is beneficial to the dynamic performance of the loop. The resulting double closed-loop structure improves steady-state and transient current-tracking performance. In addition, stability analysis of the proposed strategy is also performed. The proposed control approach is compared with PI. To verify the feasibility of the proposed scheme, an experimental prototype was constructed and tested to confirm the superiority of the proposed method in terms of dynamic performance. Full article
