In high power applications, power division methods for AC high power converters and machines are used. The rated power of the elementary converters and/or machines becomes lower when the number of converters and/or machines increases. Therefore, power switches with high switching frequency can be used. Then, the current and torque ripples would have theoretically lower amplitude. The speed control of a double stator synchronous machine supplied by two independent voltage source inverters, which is an application of power division, is studied in this paper. After presenting the system under consideration, three strategies of current control are treated. The speed control method is also discussed.
