Strength Pareto Evolutionary Algorithm for ...

This work deals with a Neutral Point Clamped multilevel inverter without balancing the voltage boundaries of DC bank capacitors and without dedicated EMC filters. To achieve this goal, a control over Modulated Hysteresis Current and a specific low-pass passive filter are implemented. The control strategy is associated with low and constant frequency mono carrier signal. The different components of the filter and the ones of the control are simultaneously designed by a genetic algorithm. The simulated and experimented values of voltage THD, current THD, and load power factor, underline the improvements brought by the present approach.
