However, the development of pulsed power generator using programming is difficult in noise problems and others. The present work aims to develop a high-performance pulsed power generator using FPGA and a personal computer (PC). The pulsed power generator consists of a pulsed power generator with magnetic pulsed compression (MPC), a charger, a controller using FPGA, a universal serial bus (USB) connection circuit and a software running on Windows PC. The software running on PC is written with Visual C#, and has a graphical user interface (GUI). This easy operational system can control several functions, such as output voltage, pulse interval, pulse repetitive rate and pulse number. The developed pulsed power generator driven by FPGA and PC is applicable to many fields such as sterilization, water treatment and bioelectrics.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127389035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ceramic composite resistors, which demonstrate high peak tempera-ture limits and high power handling capabilities in low inductance packages, are attractive choices for these applications. A thermodynamic model of one such resistor is presented to better understand their use under repetitive high power stresses and the operating conditions that lead to thermal failure. This model is used to simulate the peak temperatures generated by a series of maximum rated-energy impulses, periodically delivered as to meet the maximum rated average power of the device. To experimentally validate the model, the resistor was sub-jected to similar voltage stresses and the surface temper-atures are compared.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116973475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

S. Army's need for compact, lightweight pulse switches. Following the successful demonstration of a 3.5 cm2 silicon Super-GTO, Silicon Power Corporation re-designed the emitter layout and increased the device footprint to create a switch optimized for use in high-current, wide-pulse applications. The 7 cm2 silicon “Stitch” Super-GTO was developed to block 7 kV. The 2x increase in die size actually results in a 2.5x increase in active area because a portion of chip area that was previously taken up by perimeter high voltage termination is now used for conduction. The Super-GTOs were evaluated at the Army Research Laboratory in a low-inductance pulse-forming network. Pulse current was successfully stepped up as high as 35 kA, corresponding to a current density of 5 kA/cm2 over the chip's footprint. This corresponds to 7 kA/cm2 over the active emitter area, when the edge termination is excluded. Compared to Silicon Power's original device, the new larger component conducted 40% higher current density. The 35 kA current pulse had a width of 125 µs and an I2t of 9.2 ×104 A2s. The 10–90% rise of the current pulse was 2.4 kA/µs, and the maximum on-state forward conduction drop was 28 V. Given good processing and packaging yields, this larger Stitch Super-GTO can greatly reduce the size of high current pulse switches.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116458278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dimensions of such converters are found using simple relations from geometrical optics, which represent the electromagnetic fields with rays propagating at the speed-of-light for modes with large azimuthal indices m. However, even for small m such an approach allows one to find dimensions close to the optimal one, although necessary corrections obtained from cumbersome experiments for conversion coefficients and frequency bandwidths are required. In this present work using computer simulations with the Agilent HFSS [1] code we find the corrections to optimal dimensions giving maximal conversion coefficients over wide frequency bandwidths for such mode converters.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124695811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
