Investigation on stacked cascade multilevel inverter by employing single-phase transformers
Engineering Science and Technology, an International Journal, 2016 In the present paper a new version of multilevel inverter is investigated. This new version is based on hybrid association of commutation cells with H-bridge cells. The association allows a significant reduction of the volume of the capacitors.

Fabrication and experimental analysis of multiple-winding transformers for multiphase supply
Measurement + Control, 2020 This paper aims to fabricate multiple-winding transformers for polyphase supply that means more than the classical three-phase supply. Usually, transformers do not change the phase, that is, from single phase to three phase or vice versa, but according ...
