PM BLDC motors are designed for an output power of 22W. The output power is calculated by measuring the blade characteristic of the fan. Weight & cost of active materials in both designs are compared. It is shown that even though weight of ferrite motor is approximately 1.47 times that of bonded NdFeB motor, but overall cost of the motor is only 77.8% that of bonded NdFeB motor. Also, it is possible to achieve comparable efficiency using ferrite magnets.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"45 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":"121558525","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}

Because of their quick response and accuracy of the vector control technique, vector controlled PMSM drives are good option for many applications. This work mainly deals with design and hardware implementation of vector controlled PMSM drive using dsPIC30F6010A controller. In order to complete the drive, field weakening region is also included. In field weakening region PI controller based parameter independent technique is implemented in hardware. Introduction of field weakening region made the drive robust to the DC link voltage drops. In this work mathematical model is derived initially, followed by design of PI controllers for the closed loop system. Stability analysis is done in order to prove the robustness of the design. Later simulation studies are carried out before going for hardware implementation. Necessary hardware was built and the vector control along with field weakening region is implemented using a low cost DSP by using inline assembly coding. Simulation and hardware results validates the design of the system.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"32 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":"131417835","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}

They are incapable of generating reactive power and hence their reactive power is invariably supplied by capacitors connected across their magnetizing circuit. Therefore, the foremost design constraint of SEIGs is the evaluation of optimum excitation capacitance which fulfills their reactive power requirements for variable loading conditions. This paper presents a detailed steady state modeling and analysis of a single phase, two winding SEIG to evaluate its optimum excitation capacitance for resistive as well as inductive static loads. The steady state model of SEIG is developed through Matlab M file. Validation of simulation results is carried out through experimental tests on a single phase prime mover driven induction motor operated as SEIG.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"22 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":"131601212","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}

Furthermore, constituents of the feeders at primary distribution level are also unknown. In partially deregulated developing countries implementation of Time of Use tariff becomes a challenging task. This paper addresses this crucial issue where using data mining techniques, the load profiling at primary distribution level is carried out. Load Profiles are clustered into three major sectors commercial, industrial and residential using K-means algorithm and Silhouette analysis, then an optimization problem decomposes the load of primary feeder in terms of commercial, industrial and residential sectors. Time of Use tariff is then designed using signature profiles obtained by clustering in order to flatten the load curve and composite elasticity of demand is obtained by decomposition of feeder. The result are obtained on actual data of NYSEG system.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"72 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":"126441592","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}

Besides, it alleviates the voltage balancing problem and lower components count compared to NPC and cascaded multilevel inverters.

This non-minimum phase behaviour poses several challenges to control design like initial inverse transient response to step changes, smaller bandwidth etc. Conventional One Degree of Freedom (1DOF) controllers, when applied to Pulse Width Modulated (PWM) boost type DC-DC converter suffer from the compromise that has to be made between the set-point response and disturbance rejection. The 2DOF-PID control scheme provides an extra degree of freedom to overcome above mentioned shortcoming. In 2DOF-PID, the feedback controller is designed through Direct Synthesis (DS) approach, where the controller transfer function is derived using Maclaurin series. Further, the rapid prototyping tools such as FPGA based Xilinx System Generator (XSG) facilitate quick realization of real time controllers before they are finally used for field testing. The results obtained by implementing controller in real time FPGA environment, using Hardware in the Loop (HIL) techniques, show the robustness of the presented control scheme to regulate the output voltage of boost DC-DC converter system.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"259 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":"121349332","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}

It is based on cascade connection of multiple identical modules using IGBTs as switching devices. In each MMC module, the control circuit consisting of gate drivers is powered from a dc supply derived from the local capacitor. The module capacitors need to be pre-charged, to power the control circuit. If a fly-back converter is used to generate the power supply for driving the control circuit, the module capacitor voltages are becoming unstable during pre-charging. This paper proposes a method for stabilizing the same. By using an open loop forward converter with a linear regulator at its output, the module capacitor voltages can be maintained stable during the pre-charging of MMC. This method allows simultaneous pre-charging of module capacitors directly from the dc bus, without using any auxiliary supply. This solution is verified experimentally in the laboratory.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"706 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":"116511953","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}

It ranges from data transmission to grid management. In this paper, the use of power line communication in DC grid for control is discussed. Different approaches has been previously used to make the grid impedance time invariant for power line communication and resistive to converter noises. However, they do not consider the effect of those approaches on stability of the grid during different load conditions, especially when the grid is dominated by constant power loads. The use of decoupling inductors at each source and load in a DC grid is one of the common approaches. The stability issues in a DC grid for household application are discussed using Matlab Simulink. Resistive and constant power loads will be used for comparison. Using decoupling inductors introduces oscillation in the DC grid which may lead to system collapse depending on the value of decoupling inductors, the grid capacitance and the complexity of the DC grid.","PeriodicalId":124701,"journal":{"name":"2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"24 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":"132975223","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}
