The parallel AC-DC converters of traction control system for high speed train require accurate PLL (Phase-Locked Logic) method and synchronous PWM algorithm with phase delay control to implement unit power factor and input current harmonic reduction. The phase delay control of parallel converters driven by individual controllers is difficult. The proposed hybrid PLL algorithm detects the input voltage phase angle more accurately and improves the performance of phase delay control. The hybrid PLL algorithm consists of two kinds of method which calculate simultaneously the phase angle of input voltage. The single-phase AC-DC converters are connected in parallel through main transformer. The first PLL algorithm calculates the phase angle of primary input voltage adopting the digital APF (All-Pass Filter) and it has robust characteristics against the disturbance of input signal compared with conventional zero-crossing detection method by hardware circuit. The estimated phase angle of this algorithm is used for unit power factor control and instantaneous input current control. The second PLL algorithm generates the common reference signal for synchronous PWM by measuring the amplitude of input voltage at the near zero-crossing point. This paper describes the implementation of hybrid PLL algorithm adopting two different kinds of PLL method in detail. The feasibility of this algorithm is proven by experimental study on parallel converters (1.25MW×4) for high speed train.","PeriodicalId":105539,"journal":{"name":"IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131471030","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}

Medium voltage drives have also benefited from the favorable application characteristics of multiphase machines, as well as advances in semiconductor technology. Although high voltage and current device technology has advanced significantly, device switching losses remains as one of the main design limitations in medium voltage drives. This limits the converter's switching frequency, causing degradation in the connected machine's performance due to an increase in torque ripple. This paper investigates the performance of various multiphase induction machines when fed from a quasi-square wave inverter. The inverter topology switches at the fundamental frequency to limit inverter losses, a highly desirable feature in medium voltage applications. Four multiphase induction machines with three, five, seven and eleven phases are designed and used in the comparison study. Finite element analysis is used to determine their parameters. The investigation aims to provide a clear understanding of optimal machine-converter matching criteria based on minimum torque ripple and maximum torque gain.","PeriodicalId":105539,"journal":{"name":"IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130875942","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}
