Intelligent methods of investigation of windings are one of the methods being introduced more and more nowadays. In this study, we propose an intelligent method for identification of the parameters of the high frequencies and localization of faults in a transformer winding. For this diagnosis, Particle Swarm Optimization (PSO) method is used. We validate(More)
In this paper, a novel single phase inverter structure for pre-calculated switching using polarised capacitors as harmonics filter is proposed. This structure is developed to obtain infinite value for the input impedance to eliminate the current flow in the capacitor, and zero value for the output impedance to minimise the voltage drop. The single-phase(More)
Abstract: This paper presents a new method to decrease the switching frequency of novel harmonic elimination Pulse Width Modulated (PWM) strategy for three-phase inverter. The torque ripple of the induction motor can be dramatically reduced by the new PWM technique. The three-phase inverter is associated with a passive LC filter. The commutation angles are(More)
In this paper, we propose a new strategy for Direct Torque Neural Network Control, compatible with a voltage inverter three level and exploit artificial intelligence tools namely: neural networks. In addition, the use of multi-level inverter and the artificial techniques contribute to improved performance of the control of the wind energy conversion system.(More)
