SVM Implementation of the 4-Switch Non-Inverting Buck-Boost Y-Inverter

This paper proposes an innovative modulation and control approach for the recently introduced Y-Inverter. With relevance specifically to the 4 -switch non-inverting buck-boost configuration, a methodology is put forward, which uses spacevector modulation of the input-side buck-legs and open-loop constant-duty switching of the output-side boost-legs. The proposed approach enables simplified control and its hardware implementation burden, while at the same time maintaining all the benefits of space-vector modulation, in the various schemes, which have been abundantly proposed for the most diverse application needs.
