In order to overcome the challenge of processing electric energy in high power systems with minimal losses and high energy quality, this work presents the implementation and analysis of a modulation technique applicable on both most well-known multilevel inverter structures - neutral point-clamped (NPC), and flying capacitors (FC) - to reduce the stresses across the semiconductors devices, and to improve the total harmonic distortion of the output voltage. Throughout the work, the necessity to digitalize the proposed technique has been evidenced due to the high complexity and low reliability inherent to the analogical approach. Thus, the digital controller FPGA has been chosen, as it is easy to program and reconfigure, works at high...
