Indirect 3D-Space Vector Modulation for Matrix Converter [PDF]

open access: yesEngineering, Technology & Applied Science Research, 2018
This paper discusses the indirect space vector modulation for four-leg matrix converter. Four-leg matrix converter has been proven to be a reliable, cost-effective, and compact power electronic interface to supply unbalanced or nonlinear loads. However, the added fourth leg has shifted the inverter side modulation from simple two-dimension SVM into ...
