To achieve the requirement of the SHE-PWM such as a desired fundamental magnitude and the elimination of the low order harmonics contained in the output voltage, two heuristic and evolutionary algorithms were used. The problem of the SHEPWM is presented by a constrained nonlinear objective function which has to be minimized. The main aim is the calculation of the switching angles vector solution presenting the best minimal value for the objective function. The results obtained with the present application show the effectiveness of the use of the Particle Swarm Optimization. On the other side, the application of the PSO with SHE-PWM is a promising solution which can make a great improvement with different power electronics converters.

Stabilization by New control technique of the input DC voltages of five-level diode - Clamped inverters. Application to double star induction machine
2012 2nd International Symposium On Environment Friendly Energies And Applications, 2012

We propose a cascade circuit consisting of a FLDC rectifier a FLDC VSI. First, the different cascade parts and their control strategies are presented. The stability problem of the input DC voltages of the inverter is investigated. To remedy to this problem, two solutions are proposed: the first one uses the linear feedback control algorithm and the second one uses the non-linear control by the Lyapunov technique at the FLDC rectifiers. As an application, the performances of the double star induction machine (DSIM), as fed by the cascade, are observed. The obtained results are full of promise concerning the use of multilevel diode clamped inverters in high voltage/high power applications such as electrical traction.
