Proportional Integral Estimator of the Stator Resistance for Direct Torque Control Induction Motor Drive

The artificial neural network used to detect the fault in electrical machines and can increase the function of new entry detection when compared to the conventional method. In proposed artificial neural network has increased the precision and stability of system performance. The time-area vibration signs of a pivoting machine with ordinary and flawed apparatuses are handled for highlight extraction. The separated elements from unique and preprocessed signs are utilized as contributions to both classifiers in view of ANNs and SVMs for two-class (typical or blame) acknowledgment. The quantity of hubs in the concealed layer, if there should be an occurrence of ANNs, and the extend basis work section parameter, in the event of SVMs, alongside the choice of information components are enhanced utilizing genetic algorithm (GAs).

Generally induction motor drives posses higher harmonic contents in line voltage and current due to high switching frequency used in inverters. Conventional induction motor drives employ two level voltage source inverters which has THD in level of 50%. This paper presents a switched z-source multilevel inverter which has voltage boosting capability and has lesser THD level in comparison with conventional two level voltage source inverters. This drive is fed from a photo voltaic source because of its voltage boosting capability. A single phase five level switched z-source inverter is initially designed and considered as single cell and three such cells are created for powering three phase induction motor. The proposed three cell PV source switched z-source multilevel inverter for three phase induction motor is simulated in MATLAB/Simulink software to verify merits of proposed IM drive

This paper presents a new switched z-source multilevel inverter powered from a photovoltaic source. Addition of a power electronic switch in conventional z-source network provides excellent voltage boosting capability with moderate power rating which makes it suitable for low voltage photo voltaic applications. Proposed topology consists of single dc source, six power switches, two diodes, four capacitors and two inductors comparing to conventional five level schemes proposed topology contains less number of switches and passive elements. This scheme produces voltage waveform with lesser harmonics and shows lesser THD percentage by using different modulation index of multi carrier level shifted PWM technique. Proposed switched z-source multilevel inverter is implemented using MATLAB software and results are presented to verify merits of the scheme.
