Abstract

The efficiency of the system is a very important parameter for high power electrical drives applications,. Moreover, in the system the efficiency of the power converter play a fundamental role and for this reason, the soft switching modulation techniques represent the best choice. This paper presents a novel computational method for harmonic mitigation on the output voltage of a five-level, three-phase Cascaded H-Bridge Inverter without solving non-linear equations. Through this simple approach the Working Areas have been identified in which the harmonics reference have minimum amplitude possible. Moreover, polynomial equations to evaluate the control angels have been found. In this way, through the polynomial equations can be possible to approximate the trend of the control angles versus fundamental amplitude and without solving nonlinear equations the control angles can be evaluated. The obtained polynomial equations can be easily implemented in a digital system to real-time operation. The paper also presents the circuit simulation analysis in MatLab/PLECS environment.
