First, a relationship between the measured amplitude and fault development time was established using multi-sensor measurement technology, revealing the variation pattern of multi-parameter signals during the creeping discharge process. Second, the mechanism characteristics of creeping discharge development process were revealed in conjunction with experimental phenomena. Finally, based on multi-parameter signals and mechanism characteristics, the discharge process is divided into three stages: slow development, rapid development, and pre-breakdown. The discharge mechanism characteristics at each stage show a significant correlation with the measured amplitude. This study provides important references for the in-depth understanding of the creeping discharge process and the synchronized detection of multi-parameter sensors.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 5","pages":"871-879"},"PeriodicalIF":1.3,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143943854","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 portable pulse power supply based on a high-gain boost circuit powered by lithium batteries. It significantly provides the gain of the boost circuit through the combination of inductance and capacitance, while reducing the turn ratio of the pulse transformer, minimizing the leakage inductance and volume of the transformer. The prototype built in this article can achieve a voltage output of 05 kV, and its frequency and pulsewidth can be continuously adjusted. The size of the main circuit is only <inline-formula> <tex-math>$16times 10times 8$ </tex-math></inline-formula> cm. It can work normally and stably under both resistive loads and dielectric barrier discharge (DBD) loads. Compared with the pulse generator of a traditional boost circuit, the efficiency is improved by about 10%. The results show that compared with traditional pulse power supplies, the pulse generator based on the high-gain boost proposed in this article has significant advantages in portability and efficiency.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 5","pages":"988-995"},"PeriodicalIF":1.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143943851","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}

However, the existing feeder structures are bulky and heavy, restricting handheld use in a narrow and small space. This article presents a new type of compact microwave plasma electrodeless UV lamps based on a coaxial structure that helps cut overall weight remarkably compared to rectangular waveguide and microwave oven lamps. Besides the simple structure design, the proposed microwave plasma UV lamps have significant advantages in breakdown power and microwave energy efficiency. With an ignitor linked to the inner conductor, argon discharge can be easily trigged at an input microwave power of 60 W (4 torr), and the breakdown power can further drop to 50 W with mercury. For the energy efficiency of power coupling from the incident microwave to the discharge, a pure argon lamp has over 90% energy efficiency below 80 W, while an argon-mercury lamp achieves this above 120 W. These lamps thus hold great promise for resin curing, bacteria inactivation, pollutant degradation, and wastewater treatment.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 5","pages":"914-921"},"PeriodicalIF":1.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143943839","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}
