IEEE 519–1992 Standard has specified certain limits for the harmonic currents and voltages. According to this, the users should limit harmonic current and the supplier should limit harmonic voltages. The harmonic currents and voltages injected at the Point of Common Coupling (PCC) by the end users and utility are to be within the limits, specified by IEEE Standards. Phase Angle Diversity method is a simplified approach to predict harmonic limit compliance. It incorporates the potentially significant effects of diversity factor and Attenuation factor of different loads. It also gives the effect of power variations on system harmonic current. Results are provided in graphical format and account for variations in number of loads and load powers.","PeriodicalId":156837,"journal":{"name":"2011 1st International Conference on Electrical Energy Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131392935","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 converter employs high power IGBT modules on the high voltage and low voltage sides. This paper presents the theoretical analysis and experimental results of turn-off performance of those high power IGBTs with capacitive snubbers. The turn-off performance of the 1200V, 300A ultrafast IGBT and 600V, 760A trench IGBT has been analyzed with and without a snubber capacitor. The influence of variation in snubber capacitor and variation in gate resistance on the IGBT performance is discussed. This gives a better understanding of IGBT characteristics during the turn-off transient. Experimental results show that the snubber capacitor reduces the voltage stress and switching losses significantly during turn-off. The direct mount snubber outperforms the wire-ended snubber for the same value of capacitance; hence they are suggested for high frequency, high power applications.","PeriodicalId":156837,"journal":{"name":"2011 1st International Conference on Electrical Energy Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114143865","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}
