In recent years, multi-level inverters have gained significant attention in the field of power electronics due to their ability to provide higher voltage levels and improved output waveform quality compared to traditional inverters.
In this context, this paper focuses on the analysis, design and experimental validation of a multilevel voltage source inverter (VSI) scheme based on H-bridge cells with a modular and scalable structure for its application in power electronic converter circuits.
Over the years, researchers have developed various multilevel inverter topologies beyond the conventional neutral-point-clamped (NPC), flying capacitor (FC), and cascaded H-bridge (CHB) structures to address the limitations of the switch count, complexity, and cost.
Although traditional multilevel inverters (MLIs) offer several advantages, some significant limitations restrict their performance, especially in high-power and high-voltage applications: Complex Design and Control Structures: Traditional MLIs require multiple switching devices and complex control algorithms.
