Usually a lower order and simple controller for IFOC IM exhibits satisfactory nominal tracking performance, but may not provide the required robustness against unstructured uncertainty. A robust compensator can be plugged into the system along with the existing controller and it introduces additional robustness against unstructured uncertainty.

The process of magnetization requires generation of intense magnetic fields in close proximity with the magnetic material to be magnetized. The fields however need to be produced for a short time of the order of a millisecond. The intense magnetic field is produced by passage of a very heavy current through a coil or set of coils consisting of a few turns of copper wire or tube for a short duration, though in general, iron is used as a core material and coreless coils in some applications. Design of the core and winding shape, gauge of wire, and number of turns are determined by the desired magnetization profile. The permanent magnet material in an impulse magnetizer is typically magnetized by the discharge current of a large capacitor bank. The magnetizer generates short duration magnetic fields in the range of 100-200 Gauss within the sample coil. The capacitor bank is first charged to the desired voltage (corresponding to the desired field). It is then discharged through the coil very quickly using a high capacity SCR as a switch. Because very high current levels are involved, the coil and all circuitry are totally contained in a single case. The proper protection circuit is provided for SCR circuit. A novel technique for magnetizing the permanent magnets is presented. Simulated waveforms of voltages and currents are presented. The simulated results are verified with the hardware results.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123158343","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 polygon connected autotransformer with multi windings per phase at different phase angles is used to realize the proposed 24-pulse AC-DC converter. The design of proposed autotransformer is presented along with the necessary modifications required for making it suitable for retrofit applications, where presently a 6-pulse diode bridge rectifier is used. The proposed 24-pulse AC-DC converter is able to eliminate upto 21st harmonics in the supply current along with the power factor improvement close to unity in the wide operating range of the drive. The effect of load variation on VCIMD is also studied to demonstrate the effectiveness of the proposed AC-DC converter. A set of power quality indices on input ac mains and on DC bus for a VCIMD fed from six-pulse and proposed AC-DC converter are presented to compare their performance.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123409380","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 wind driven self-excited induction generator (SEIG) and other network components are modeled and simulated using Matlab/Simulink. The variable voltage and frequency of a generator is first rectified and the DC power is then transferred to the load through a DC link converter. By adjusting the modulation index of the PWM inverter, maximum power can be obtained from the system and the terminal voltage can be maintained constant under varying wind velocities and load conditions. Design of two neuro controllers are proposed: 1) to maximize the power extraction from the wind turbine for heating loads and 2) to regulate the terminal voltage for voltage sensitive loads.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123563385","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}

Electric vehicle requires fast torque response and high efficiency of the drive. Speed sensorless DTC induction motor drives without mechanical speed sensors at the motor shaft have the attractions of low cost, quick response and high reliability in electric vehicle application. To replace the sensor, the rotor speed is estimated from sensed stator voltages and currents at the motor terminal. This control strategy is extensively used in electric vehicle application. Modelling and simulation is carried out in standard MATLAB/SIMULINK software. The drive performance is studied for acceleration, braking and flux weakening (above rated speed).

The single phase voltage source inverter is used to obtain the ac voltage source. This proposed converter could return the energy stored in the phase coils after turning off the phase switch. A buck boost converter is added to the topology for controlling the amount of energy recycling to the source. This enables the improvement of average torque in SRM. The motor torque is controlled by adjustment of the current of the inverter. Also the relative position angle between stator and rotor can be controlled with the same converter. Simulation for novel SRM power converter connected to the voltage source inverter is carried out using PSIM 6.0. The torque output of the proposed converter has been compared with the torque output of the conventional SRM power converter.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128003855","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}
