With a single active switch in addition to the diode bridge rectifier, the converters are capable of drawing a high-quality input-current waveform naturally at nearly unity power factor. Thus a simple 3 phi AC-DC high power factor rectifier is obtained. Simulation and experimental results are supplied to demonstrate the validity of the concept.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125452030","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}

This strategy appears to be very promising in single-phase applications, for which nonredundant switching configurations do not affect the capacitor voltage balance.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121448776","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 double nonlinear resonant pole converter exhibits lower switching losses, reduced parasitic oscillations, and lower overrating of the switching devices.

This should not increase the cost of the inverter, nor will any additional or different control schemes be needed.

The main factor involved in proximity losses, the effect of window fill, is studied. Analytical solutions to the two-conductor problem show that the proximity effect can increase losses by up to three times the isolated skin effect loss. A 2D finite element analysis is employed to study systems consisting of a large number of conductors. It is shown that the introduction of conductor-to-conductor spacing can reduce proximity losses.
