Throughout this Dissertation, the reader will find a comprehensive review and discussion about the state of the art and future perspectives of VSI implemented in four-wire applications. The three-dimensional Space Vector Modulation problem for this kind of converters is extensively discussed and a simple modulation algorithm for a three-level four-leg NPC converter is proposed and successfully validated in an experimental rig. Afterwards, the proposed modulation technique is implemented in an aerospace application as a 400Hz, 110V, Ground Power Unit (GPU).
