Traditional methods account for the inductance of the magnetic core coil by including the core’s influence in the total magnetic flux generated by the coil. This article models the core’s influence as an interaction between the coil and an additional coil. The self-inductance of an individual coil, when positioned in a ferromagnetic core, is divided into the self-excited inductance of the coil and the mutual inductance between the coil and its mirror coil due to the ferromagnetic core. The mutual inductance between coils is categorized into coil-to-coil mutual inductance and coil-to-mirror coil mutual inductance. The analytical method is derived and implemented in MATLAB, demonstrating that the solution speed surpasses that of traditional analytical calculation methods. Moreover, this method is applicable to various core and coil shapes. Then, the proposed analytical method is validated against finite-element analysis and experimental. Based on this analysis method, this article presents an innovative method for accurately measuring the self-inductance and mutual inductance of windings without requiring large, expensive cores. By using several lightweight coil configurations, this approach reduces material and manufacturing costs while streamlining the measurement process. Comprehensive validation shows that this new technique matches the accuracy of traditional methods, effectively addressing the effects of the core. Overall, the method enhances measurement precision and transforms inductance evaluation, promising greater efficiency in electromagnetic design and applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 6","pages":"1267-1276"},"PeriodicalIF":1.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314859","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 power supply used to generate and sustain the gliding arc discharge process is a core component of the plasma source. High-voltage and high-frequency power supply based on Mazzilli’s zero voltage switching (ZVS) circuit have the significant advantages of simplicity, stability, and low cost. However, drawbacks such as heat generation in the drive circuit, limited voltage regulation range, and non-adjustable output frequency have restricted the application of Mazzilli’s ZVS circuit in plasma biomedical research. To overcome these shortcomings, an improved ZVS circuit was designed with power control and switch-capacitor array in this work. A compact rotating gliding arc plasma source was developed with adjustable power and frequency control. Its frequency range is 35–72.5 kHz and the power range is 50–200 W. Optical emission spectroscopy (OES) diagnostics indicate that the products of the proposed plasma source can be flexibly regulated. For instance, by fixing the power at 50 W and adjusting the frequency from 35 to 72.5 kHz, the emission intensity of OH increased by 39.7%. Besides, the plasma source can be powered by a lithium battery and weighs only 5 kg.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 6","pages":"1341-1349"},"PeriodicalIF":1.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308413","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 presents a new type of armature structure, termed the multiconductive armature structure (MCAS), designed to enhance acceleration performance in asynchronous induction coil launchers. It analyzes the impact of the new armature structure on the propulsion performance of electromagnetic coil launchers. By establishing a mathematical model for the MCAS armature and designing the orthogonal experiment, the study investigates the effects of three parameters: the axial length of the circular rings located at the rear and front ends of the armature, and the distance between these two armatures, on the exit velocity and acceleration efficiency. The results indicate that the length of the rear armature ring has the most significant impact on the final propulsion performance, while the interactions among various factors influence the overall propulsion effect. And the experimental results demonstrate that the MCAS armature has a higher exit velocity, greater propulsion efficiency, and a lower armature weight ratio compared to conventional armatures. This novel armature structure provides a new design solution for asynchronous induction coil launchers.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 6","pages":"1378-1386"},"PeriodicalIF":1.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308338","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}
