This technology is an environmentally friendly solution that significantly reduces costs and energy consumption, eliminates the need for liquid handling, and minimizes environmental impact.

The obtained data demonstrate the feasibility of uniform plasma-assisted healing of cathode powders with high thermal efficiency (0.30–0.33 kWh/kg). These findings confirm that the proposed plasma-based regeneration process can achieve rapid and energy-efficient recovery of degraded cathode materials. The values of the main parameters are taken from the CFD-based heat balance (this work) rather than from experimental measurement; the sensitivity is ±0.03 kW h/kg to the carrier gas prehealing, powder, and powder specific heat.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1300-1305"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional armature winding self-excitation synchronous pulsed alternator contains high-power carbon brushes and slip rings in its structure, which limits its development toward higher rotational speed and higher power. In recent years, many scholars have proposed a variety of new topologies for brushless air-core pulsed alternators, eliminating the carbon brush and slip ring structure. However, the magnetic field and current frequency on the stator side are relatively high, resulting in huge copper loss under pulsed discharge conditions. This article optimizes stator windings of a brushless air-core pulsed alternator and analyzes the influence of different Litz wires and flat wires on the slot fill factor, dc resistance, and ac resistance. The theoretical calculation model and finite-element simulation model of different wire types are established. The effects of wire types and transposition method on dc copper loss, eddy current loss, circulating current loss, and discharge current peak under extreme discharge conditions were obtained. On this basis, combined with common pulsed discharge conditions, a comprehensive comparison of copper loss and discharge characteristics during the discharge process of different wire types was carried out. The results show that selecting the appropriate wire type according to different loads and stator electrical frequency can help improve efficiency and discharge performance.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1895-1902"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article proposes a sequence solution strategy based on charge equivalent. Based on the principle of equal charge amounts during the discharge process, the relationship between the current waveforms and the number of modules at different stages is obtained. Then, the triggering sequence of each module is solved according to the set current requirements. A typical representative system was established to verify the feasibility and accuracy of the above solution strategy. The results show that the triggering sequence obtained by the solution strategy can make the discharge current meet the requirements and improve the solution efficiency. The sequence solution strategy based on charge equivalent can not only avoid complex mathematical calculations to obtain the triggering sequence, but also effectively improve the discharge success rate of the engineering test.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1909-1915"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LTSPICE simulations and experiments have demonstrated the feasibility of two novel TCLCG circuit configurations that enable the inversion of the first half-cycle of the oscillating output voltage signal with respect to the polarity of the charging voltage, distinguishing them from conventional TCLCG designs. In the first solution, this is accomplished by modifying the wiring of the last-stage transformer. In the second solution, the first-stage transformer is modified, and an additional inductance is added at the generator output to earth ground. Here, the odd-numbered capacitors facilitate rapid voltage multiplication, while the even-numbered capacitors already have the correct inverted polarity. Consequently, the development of a bipolar TCLCG became feasible, consisting of a conventional noninverting and an inverting generator branch in parallel, both controlled by a single closing switch. A six-stage bipolar TCLCG, comprising matched three-stage noninverting and inverting generator branches with synchronized oscillation frequencies, achieved a peak differential voltage of 183 kV across a resistive load of 447 k<inline-formula> <tex-math>$Omega $ </tex-math></inline-formula> at a charging voltage of 21.6 kV. The contributions from the two generator branches summed almost perfectly, with an average loss of 1.2%. The rise time of the generator’s differential output signal was 25 ns. The achieved peak-to-peak differential voltage reached 301 kV. Potential applications include the control of symmetrically designed antennas.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1377-1381"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
