Potential distribution can be determined by different field-limiting ring and field plate design which can be described by solving Poisson's equation in one dimension briefly. In this paper, the influence of design factors such as spacing between main junction and ring, ring width, and field plate width on potential and strength of surface electric field distribution are analyzed. From the simulation results, the relationship between those factors and potential and strength of surface electric field distribution can be found. Understanding the effect of design factors upon the junction termination edge, multi field-limiting rings and field plates of high breakdown power devices can be designed.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"228 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116401267","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}

It is based on the \"phase advance approach\", which was proposed for brushless DC motor drive in 1995. This paper completes the \"phase advance approach\" theory in several aspects: a) the stator resistance is taken into account in the analysis and calculation of phase reference current; b) the situation where the back EMF is smaller than the applied voltage is also taken into consideration; and c) an analytical equation to calculate the advance angle is also derived. The obtained equation are therefore more general than those in the prior art. Extended simulation results demonstrate the validity of the approach.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124462991","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}

Furthermore, torque characteristics of the HECSM for different field currents are explored. A 2 kW prototype is manufactured, and the experiment for field-control capability is carried out. Experimental results coincide well with those of FEA.

These equations are governed by a multidistributed value problem (MDVP) which makes this problem a difficult numerical one, non accessible by traditional solvers. This article shows thanks to the properties of Ck spline functions that we can integrated such problems by judicious choices of the initial vectors and simulated annealing methods.

An accurate harmonic current control for shunt active filters can be achieved using resonant compensators. In this paper, the current control system is designed to operate with a single dq reference frame, synchronous with the 50 Hz supply voltage, for the compensation of all main harmonic currents, 5th, 7th, 11th and 13th. The design procedure and the principle of the proposed control method are presented.
