“…Although the sinusoidal power supply has the advantages of simple structure and lower prices [18][19][20][21][22], existing research demonstrates that the use of all solid-state pulsed power supplies (i.e., unipolar or bipolar Marx modulators) is more efficient. Therefore, there has been much research and many applications with all solid-state Marx modulators for DBDs [23][24][25][26][27].…”

“…Efficiency is the most crucial product feature in scientific applications and industry, especially for DBDs. At present, the study of the efficiency of an all solid-state Marx modulator is primarily focused on resistive load [25][26][27]. A generalized solid-state Marx modulator efficiency was calculated from the ratio between the input power (from the measured average voltage and current values) and the output power delivered to the load (from the measured current and voltage waveforms) using resistive loads, and its was 85.5% [25].…”

“…The output energy to the 50 Ω load resistor was calculated from the waveforms, giving a total energy efficiency of 59% at a repetition rate of 1 kHz [26]. The repetitive output voltage of the solid-state pulse generator was a 200 Ω resistive load with a 1 kHz repetition rate, and the total power efficiency of the pulse generator was 86.64% [27].…”

For an all solid-state Marx modulator applied in dielectric barrier discharges (DBDs), hard switching results in a very low efficiency. In this paper, a series resonant soft switching circuit, which series an inductance with DBD capacitor, is proposed to reduce the power loss. The power loss of the all circuit status with hard switching was analyzed, and the maximum power loss occurred during discharging at the rising and falling edges. The power loss of the series resonant soft switching circuit was also presented. A comparative analysis of the two circuits determined that the soft switching circuit greatly reduced power loss. The experimental results also demonstrated that the soft switching circuit improved the power transmission efficiency of an all solid-state Marx modulator for DBDs by up to 3 times.

Big data of biological engineering and mobile control increase the complexity of system control. In order to resolve the above problems and improve biological engineering system performance, this paper proposes a large data-driven and mobile crowd embedded opportunistic control mechanism. First of all, the measurement model of established big data-driven biological embedded engineering was proposed based on the research of biological engineering with non-linear and unpredictability. Based on the characteristics of the mobile crowd terminal perception outside interference, we proposed the mobile crowd biological engineering optimization opportunities control mechanism. The experimental results show that the established control mechanism in a long-term, large-scale performance still has high performance and high temperature. In addition, under different pressure, the rate of convergence of the scheme established is superior to the biological engineering control scheme based on coordination control.

In order to overcome the limitations of the existing classical and solid-state Marx Pulse Generators, this paper proposes a new modular multilevel voltage-Boosting Marx Pulse Generator (BMPG). The proposed BMPG has hardware features that allow modularity, redundancy and scalability as well as operational features that alleviate the need of series connected switches and allows generation of a wide range of pulse waveforms. In the BMPG, a controllable low-voltage input boost converter supplies, via Directing/Blocking (D/B) diodes, two arms of a series modular multilevel converter Half-Bridge Sub-Modules (HB-SMs). At start up, all the arm's SM capacitors are resonantly charged in parallel from 0V, simultaneously via directing diodes, to a voltage in excess of the source voltage. After first pulse delivery, the energy of the SM capacitors decreases due to the generated pulse. Then, for continuous operation without fully discharging the SM capacitors or having a large voltage droop as in the available Marx generators, the SM-capacitors are continuously recharged in parallel, to the desired boosted voltage level. Because all SMs are parallel connected, the boost converter duty ratio is controlled by a single voltage measurement at the output terminals of the boost converter. Due to the proposed SMs structure and the utilization of D/B diodes, each SM capacitor is effectively controlled individually without requiring a voltage sensor across each SM capacitor. Generation of the commonly used pulse waveforms in electroporation applications is possible, whilst assuring balanced capacitors, hence SM voltages. The proposed BMPG has several topological variations, such as utilizing a buck-boost converter at the input stage and replacing the HB-SM with full-bridge SMs. The proposed BMPG topology is assessed by simulation and scaled-down proof-of-concept experimentation to explore its viability for electroporation applications.
