The rapid expansion of photovoltaics is driven by significant reduction in costs. However, given the surface requirements for photovoltaic development, utilizing water surfaces for floating photovoltaic (FPV) systems presents a promising solution. To enhance the cost-effectiveness of these systems, bifacial modules and tracking systems can be employed. While numerous experimental studies have evaluated the performance of fixed-configuration FPVs, floating tracking configurations remain underexplored. In addition, various simulation tools offer insights into different configurations, but their different assumptions often yield inconsistent results. This study focuses on the experimental evaluation of a horizontal axis tracking bifacial FPV (HT-bFPV) system. Over one year, the HT-bFPV system was monitored at the FPV test bed of “Enel Innovation Hub & Lab” in Catania, Italy. The experimental results were compared with simulated outcomes using two software tools, to assess their precision in calculating the HT-bFPV performances. The results reveal that the module temperature of the HT-bFPV system is 3 °C to 6 °C lower than the temperatures calculated by System Advisor Model and Photovoltaic system software, respectively. The yearly reference yield of 2139 kWh/kW produced a final yield of 1801 kWh/kW. The yearly performance ratio of the HT-bFPV system was 0.86, which improved by 1.8% when adjusted for temperature. The simulation results closely matched the experimental data, validating the system's performance. Furthermore, it was confirmed that the HT-bFPV system can produce up to 13.3% more energy with more potential in sites with higher latitudes compared with a similar fixed system.

This study presents a channel-type multipacting cathode and employs the particle-in-cell (PIC) and Monte Carlo (MC) simulation methods to investigate the influence of various cathode parameters, including channel material, channel aperture, axial applied electric field, and initial input current on emission performance. All these parameters are found to significantly affect the output current density of the cathode and are further optimized. The optimized cathode can achieve an output current density of 380 A/cm2, significantly enhancing the output current density of the multipacting cathode and providing valuable theoretical support for the design of cathodes with high current density.

The measurement of square wave signals with sub-nanosecond (<1> $Omega $ effectively enhances the low-frequency performance of the probe. The “ringing” phenomenon of the loop under high-resistance load is further analyzed in this study. To achieve wideband measurement, waveform distortion is effectively suppressed by incorporating a damping resistor and limiting the length of the transmission signal line. Finally, by conducting electromagnetic field simulation, network analyzer inspections, and calibrating experimental standard signal generators, we demonstrated that the proposed coaxial pulse probe has a wideband range of 10 MHz–1 GHz, a leading-edge response time of approximately 350 ps, and a measurement error of less than 3%.

Micro-concentrating photovoltaic (micro-CPV) technology has the potential to contribute to the energy transition, facilitating the shift toward more sustainable and renewable energy sources by combining minimal carbon footprint and energy demand with low levelized cost of electricity. Micro-CPV modules utilize direct normal irradiance to convert sunlight into electrical power, necessitating precise solar tracking. The performance of these modules is influenced by their alignment toward the sun and prevailing outdoor conditions during outdoor operation. The spectral conditions, along with the ambient temperature, irradiance, and wind speed, influence the current–voltage characteristics of multijunction solar cells and the optical behavior of the lens. We have developed a novel micro-CPV module concept, which is based on low-cost and high-throughput manufacturing processes. In this work, we present a prototype module in a 10 × 6 array configuration (205-cm2 aperture area, submodule class). We discuss outdoor measurements recorded over one year and the influences of various outdoor conditions. In an IEC62670-3 power rating, efficiencies of 36.0 ± 0.4% and 33.0 ± 0.4% at concentrator standard test conditions and concentrator standard operating conditions, respectively, are determined. Highest efficiencies, about 0.4% higher than at standard conditions, were attained at a more red-rich spectrum, namely at a spectral matching ratio SMR12 of 0.94 ± 0.03. Using measurements at different temperatures, we show that the planoconvex silicone-on-glass primary lens has a negligible temperature dependence. Changes in the module performance over the course of one year are discussed. Despite employing commercially available low-cost components and high-throughput processes, no significant degradation was observed during the first year of operation.

X-ray digital imaging technology can be used for visualization and nondestructive detection of power equipment, which is widely used in defect determination and anomaly detection. However, when X-ray is used for defect detection of power equipment, it remains to be investigated whether X-ray irradiation will deteriorate the properties of insulating materials or not. In this study, four kinds of insulating materials that are commonly used in power equipment, including alumina (Al2O3), epoxy/alumina (EP/Al2O3) composite material, polyether ether ketone (PEEK), and polyimide (PI), are irradiated with high-penetration and high-dose X-rays. The effects of irradiation time and atmosphere on the properties of insulating materials were studied systematically. The results show that the crystalline structure of inorganic materials and the chemical structure of organic materials are basically unchanged after X-ray irradiation. In terms of insulation properties that include dielectric property, surface flashover voltage, surface potential decay, and volume resistivity, it turns out that the insulation performance of the insulating materials tends to deteriorate after X-ray irradiation, while the degree of degradation is extremely low. In addition, the results of surface potential decay of EP/Al2O3 show that the X-ray irradiation would accelerate the dissipation of surface charge, which is in favor of the safety of power insulation.

Insufficient efficiency and transition ablation are the main problems of current electromagnetic launch device, which affect the launch performance and service life. Due to the structure of the electromagnetic launch device, common speed increasing method usually causes more severe armature-rail ablative damage. In this article, a magnetic field-regulated enhanced electromagnetic launch (EEL) was investigated through experiments, and the ablation of the device was analyzed as well. The magnetic field distribution is controlled through head and tail guidance. Achieved a significant synergistic enhancement in both launch speed and damage reduction. An experimental platform for magnetic field-regulated EEL was set up. Conduct experimental validation of conventional armature and enhanced armatures with rear-end guidance angles of 30° and 45°. Compared to the conventional armature, the speed of the enhanced armature increased by 31.9%. The armature-rail contact surface damage was significantly reduced. A study was conducted on the ablative damage of the armature under high-speed sliding friction. The tail of the conventional armature experienced severe melting, with its length reduced from 19 to 12 mm. There was no significant change in the length of the enhanced armature tails and the damage was significantly reduced. Changes in the armature-rail contact surface are analyzed based on muzzle voltage. Mechanisms for damage reduction under magnetic field regulation units are revealed. At $t =2$ ms, the conventional armature experienced transition, while the enhanced armature showed no obvious transition during its movement.

As the applications of pulse generators continue to develop in a variety of fields, so do the requirements for pulse generators. The development of pulse generators is facing many key issues, such as high-voltage drive isolation, compact design, and weight reduction. In this regard, a single-driver Marx generator (SDMG) based on series-connected switches (SCSs) is proposed in this article. The proposed SCS module improves the voltage withstand capability of each Marx stage while ensuring good synchronization of the switches, thus reducing the number of Marx stages. Moreover, in the whole Marx generator, only one switch needs to be triggered by the driver; the rest of the switches can be self-triggered by coupling capacitors. With the reduction in the drivers and Marx stages, the size and the cost of Marx circuits are significantly reduced. The working principle is first analyzed. Then, through the simulation, the proposed SCS module is verified to have a higher switching synchronization compared to the related topologies previously proposed. Finally, an SDMG prototype based on the SCS is developed. The output parameters of the SDMG are tested. The test result shows that the SDMG can output pulse with a voltage of 12 kV and a rise time of 69.5 ns. The pulsewidth can be flexibly adjusted from 200 to 1000 ns, and the size of the generator is very small, only $13times 6times 2.5$ cm.

The global energy structure is primarily dominated by fossil fuels, with coal being the main contributor to energy supply. This article proposes a combustion method based on the combination of nonequilibrium plasma generated by medium barrier discharge and water additives. The influence of different H2O atomization rates on discharge power, mass loss, and temperature variation during plasma-assisted coal combustion processes was investigated. The research findings indicate that, under a fixed power supply voltage amplitude of 13.5 kV, as the H2O atomization rate increases from 0 to 3.0 mL/min, the asymmetry of discharge current increases while discharge power decreases. When the H2O atomization rate is 1.2 mL/min, the mass loss, temperature, and combustion surface reach their maximum values. Excessive H2O inhibits coal combustion. Compared with the case of no H2O addition, at a power supply voltage amplitude of 13.5 kV and a H2O atomization rate of 1.2 mL/min, the combustion rate of coal significantly increases, and the combustion limit is extended.
