“…The most popular of these applications are food processing, water treatment, air purification, chemical industry, and electroporation process. [1][2][3][4][5] Conventional Marx generator (CMG) is the most widely used approach for the generation of high-voltage impulses. Such a generator relies on spark gap switches enclosed in pressurized insulated gas; this gives rise to several drawbacks: bulky size, instability of output signal waveform, narrow range of load impedance, and low pulse rate (tens of Hz range).…”

SummarySolid‐state Marx generators (SSMGs) are capable of generating high‐voltage pulses, with certain repetition frequency, and have a multitude of applications. Published research work targets more elaborate SSMG circuits without the existence of a specific design procedure. In this paper, basic circuit parameters (stage capacitance, duty cycle and voltage droop) of generic resistive‐loaded SSMG—producing a single/burst of pulses—are precisely modeled. Accordingly, a generalized, closed‐form analytic design algorithm suitable for any resistive‐loaded SSMG is presented; the proposed algorithm guides designers throughout the SSMG design phase and furthermore, produces parametric design curves that provide designers with an in‐depth vision of the individual effect of each design parameter on the circuit performance. To quantify the robustness of the proposed algorithm, it is used to design a simple conventional, load‐dependent SSMG architecture fulfilling specific application requirements (frequency of 10 KHz, peak output voltage of 1.2 KV, and 510‐W average power per burst). Based on the obtained design and using the derived equations, the average power per burst is calculated for different number of pulses in the range of 1–10 pulses for the simulation and the implementation. The resulting relative error between the simulation and the measurement results is found to be in the range of 0.14%–0.37%. Afterward, the proposed algorithm is used to validate the published results of a complex SSMG. The relative error between the published results and those obtained using the proposed algorithm does not exceed 2.5%; this validates the modeling behind the proposed design technique and renders it as a solution approach for any resistive‐loaded SSMG topology irrespective of its complexity.

“…The output voltage of the five-stage (comprising nine storage capacitors discharged in series) hybrid isolated all-solid-state Marx generator designed by Cheng Hsien et al is approximately 800 V with an input voltage of 100 V[26], and the rising edge of the pulse output from the device is approximately 42 ns. The maximum output voltage of the five-stage Marx generator designed by Selvakumar Ganesan et al is 49 V with an input voltage of 12 V[27], and the rising edge of the pulse output from the device is approximately 9.93 ns. Table4lists the methods used in these studies and their conclusions.…”

To meet the application requirements of pulsed power technology in wastewater treatment and other aspects (for example, a scenario that requires a high-voltage pulse source that can output a pulse with a rising edge in the nanosecond range and a device that can stabilize the pulse under high-frequency conditions), this paper designed an inductively isolated bipolar high-voltage pulse source. It consists of three parts: the primary charging power supply, the isolated driver circuit, and the pulse-forming circuit. By using inductance instead of traditional resistance isolation, using the inductance for charging and isolation, the inductance can increase the charging voltage of the capacitor, so the circuit can achieve a higher voltage output. The dual-Marx generator parallel connection design of the pulsed power supply topology, using a primary charging power supply for positive and negative polarity charging, can simultaneously output the reverse polarity and size of high-voltage pulses to achieve a bipolar output, so the load has an effect on the pulse. The equipment was selected on the basis of the design of the isolated driver circuit, primary charging power supply circuit, and pulse-forming circuit for the corresponding simulation, and in the experiment to build a principle model, the tests showed that the pulse source output pulse amplitude range was 0~10 kV (the positive pulse voltage was 5 kV, and the negative pulse voltage was −5 kV), the pulse rising edge was approximately 200 ns, the pulse width was 1 μs, and the frequency range was 0~1 kHz for the pulse source frequency. The power supply was designed to be used in applications such as wastewater treatment.

A new fifteen-level stepped DC to AC hybrid converter is proposed for Solar Photovoltaic (SPV) applications. A boost chopper circuit is designed and interfaced with the fifteen-level hybrid converters specific to Electric Vehicles’ Brushless DC Motor (BLDC) drive systems. In chopper units, the output of solar panels is regulated and stepped up to obtain the nominal output voltage. In the stepped DC-link hybrid converter configuration, fifteen-level DC-link voltage is achieved by the series-operated DC-link modules with reduced electrical energy compression. From the comprehensive structure, it is anecdotal that the proposed topology has achieved minimum switching and power loss. Elimination of end passive components highlights the merits of the proposed hybrid systems. The reduction of controlled power semiconductor switches and gate-firing circuits has made the system more reliable than other hybrid converters. From the extensive analysis, the experimental setup has reported that 7% reduction in harmonics and a 54% reduction in controlled power switches than the existing fifteen-level converter topologies. Mitigation of power quality issues in the voltage profile of a fifteen-level multilevel hybrid converter is achieved through the implementation of dsPIC digital-controller-based gate triggering circuits.
