Abstract :
This work presents transformers used by a new family of polyphase power convertors having an odd number of phases which is not a multiple of 3. The special feature of these transformers is that the judicious arrangement of their windings ensures an equitable distribution in power semiconductors, making them suitable for heavy-current industrial applications. The structure of these transformers also makes it possible to increase the number of phases of these power convertors, the effect of which is to reduce the DC ripple and the harmonic currents inflicted on the AC supply network
