Design and analysis of three-to-five-phase transformer for multiphase load

This research is focusing on a development of a multiphase transformer, or more specifically a three-to-five-phase transformer. The development of this transformer is based on the manipulation of the phasor diagram. The two input voltage phasors are added together in order to generate the output vol...
