This work presents the design and performance assessment of a scaled-down prototype of a modular gallium nitride device-based multilevel inverter. The three-phase three-level diode neutral point clamped inverter has been designed and realized for electric traction applications. The modular structure offers high flexibility to the power conversion unit, enabling testing of various device packaging. A comprehensive experimental performance evaluation of the proposed converter is conducted, highlighting the advantages and limits of the designed solution. Finally, based on the experience gained with the prototype investigated in this work, an improved design is anticipated that minimizes parasitics both in power and driving loops. This improved design is currently under development and testing.
