By sensing two line-to-line voltages, the required pulse patterns for deadbeat response can be computed in real time using the predicted voltages at 9 kHz sampling frequency. This closed-loop voltage control inherently results in a very low total harmonic distortion and a very rapid transient response with less filter capacity. The modeling technique, theoretical analysis, simulations, and experimental results are described.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129384688","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}

A historical review of PWM techniques is included. This technique is compared with the uniform-sampled, area-computation technique. It is shown that in the case of motor load, the presented method can be used at a higher frequency of operation, whereas at a lower frequency of operation, a uniform-area sampling method can be used. The sinusoidally sampled PWM technique can also be used for uninterruptible power supply systems and for a three-phase four-wire system, where it has an edge over the uniform-area sampling technique. In these applications, frequency is kept constant. The output voltage change due to load variation can be compensated by changing the depth of modulation.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127392097","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 characteristics of the inverters can be improved considerably by using certain nonsinusoidal modulating functions in place of the usual sinusoid. Two kinds of modulating functions are considered, and their impact on the inverter performance is analyzed. Both of them result in a significantly increased fundamental and reduced harmonic content of the inverter output voltage. Implementation of the optimal nonsinusoidal modulating functions is illustrated for the so called incremental PWM method, but the idea can be extended to a broad class of PWM techniques.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"33 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124966283","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}
