The speed control of BLDCM is achieved by varying the DC bus voltage of the voltage source inverter (VSI) feeding BLDCM. The BLDCM is electronically commutated using a VSI operating at low frequency switching for reducing the switching losses in VSI. A canonical switching cell (CSC) converter is used for varying the DC bus voltage of VSI. This CSC converter is operated in discontinuous inductor current mode (DICM) for achieving a power factor correction (PFC) inherently without any sensing requirement. The rotor position sensors are eliminated by using sensorless control of BLDCM. Hence, a sensorless BLDCM drive is developed as a cost effective solution for low power applications. Its performance is evaluated on a developed prototype at various speeds with unity power factor (UPF) at AC mains.","PeriodicalId":206767,"journal":{"name":"2014 IEEE 6th India International Conference on Power Electronics (IICPE)","volume":"54 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":"121572556","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 converter provides higher voltage gain moderate duty ratios. The zero voltage transition auxiliary circuit is incorporated into the circuit to provide further advantages in terms of reduction of switching losses for nearly all the switching devices. Modes of operations are identified, and then steady-state analysis is presented for design purpose. In order to verify the zero-voltage switching, soft-switching, performance of this converter simulation is carried out in PSIM. To further test the advantage provided by this converter, over hard switched converters, a comparative analysis is carried out in simulation and experiment at various loading conditions. The converter performance is predetermined for a 24 to 48 V, 25 W prototype in simulation and then compared with experimental results. Experimental measurements are in close agreement with analytical predictions.","PeriodicalId":206767,"journal":{"name":"2014 IEEE 6th India International Conference on Power Electronics (IICPE)","volume":"71 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":"126253881","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 proposed configuration eliminates the diode bridge at the front end thereby offering low conduction losses and high power quality in line with IEC-61000 standard norms. The front end converter offers fast dynamic response compounded with good output voltage regulation where the output is characterized by a low 100 Hz ripple.

This paper develops an optimal bidding strategy for 24 hourly markets over a day, for a multi-unit thermal Genco. Different fuel type units are considered and the problem has been developed for maximization of cumulative profit. Uncertain rivals' bidding behavior is modeled using normal distribution function, and the bidding strategy is formulated as a stochastic optimization problem. Monte Carlo method with a novel hybrid of Differential Evolution (DE) and Biogeography Based Optimization (BBO) (DE/BBO) is proposed as solution approach. The simulation results present the effect of operating constraints and fuel price on the bidding nature of different fuel units. The performance analysis of DE/BBO with GA and its constituents, DE and BBO, proves it to be an efficient tool for this complex problem.","PeriodicalId":206767,"journal":{"name":"2014 IEEE 6th India International Conference on Power Electronics (IICPE)","volume":"9 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":"122825659","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}

Both models are used in multiple control modes. A fictitious bus is created in both models to connect the STATCOM and to reduce the complexity of the program. The STATCOM is connected via coupling transformer impedance. The switching losses and losses in the coupling transformer are also incorporated in this model.
