| Popis: | Under the aspect of decreasing costs for power electronic elements due to mass production, machines with feeding from multiphase inverters can be considered where each slot is activated as a separate phase. The number of IGBT switches is increased, but the current rating of the IGBTs becomes very small, thus reaching the region of cheap mass production elements. Additionally, this allows a smaller capacitor in the intermediate circuit and a mechanical structure of the inverter that can be easily integrated into the machine housing. By this, the often critical du/dt problems can be reduced significantly. In the machine, new features such as an ideal sinusoidal or even rectangular distribution of electric loading and flux density become possible. Moreover, if induction machines with squirrel cage are considered, a rather free adjustment of the pole pitch is possible. In the paper, this approach and its consequences on the performance and the construction of the machine are discussed for an exemplary induction machine. |
