The BCSVM clamps any of the bus in each sector for a given switching period. The V/f control scheme is simulated in the MATLAB environment using both two and three level BCSVM. The operating characteristics of 3LBCSVM inverter fed induction motor drive during starting, step speed, and step load are tested and compared its performance with the 2LBCSVM. The torque and flux distortion of the IM for 3LBCSVM are less with less current and voltage total harmonic distortion (THD). Moreover, the capacitor voltage balance problem is analyzed in three-level diode clamped inverter and obtains the optimum switching states to balance the capacitor voltage of the inverter.","PeriodicalId":206767,"journal":{"name":"2014 IEEE 6th India International Conference on Power Electronics (IICPE)","volume":"602 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133500288","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 mathematical model of the PV panel is solved using Newton Raphson method on the real-time simulator. This can provide the output voltage and current of the PV panel for any load resistance at a given irradiation and temperature, consuming less than 50μs. By repeatedly solving the model for different values of resistances, the IV and PV characteristics of a commercially available PV panel (i.e. KT200C) are obtained for different values of temperature and irradiation.

Another five level topology, which is free from the problem of voltage collapse, is compared with the classical topology. All the control methods have been simulated in MATLAB. A variation in Total Harmonic Distortion (THD) in output voltage and output current is analyzed for each control strategy. These values are compared to the THD values obtained from another five level topology. Comparison is done for both topologies once by keeping inverter input voltage constant and thereafter by keeping inverter output voltage constant. Both static loads and dynamic loads have been used. The effect of changing load on the THD values of voltage and current has also been tabulated.","PeriodicalId":206767,"journal":{"name":"2014 IEEE 6th India International Conference on Power Electronics (IICPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122092944","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}
