An electrical machine can be made to convert electrical power while performing in its primary role of transforming electrical energy into mechanical energy. One way of doing this is to design the machine with multiple stator windings where one winding acts as a primary for drive and power, and the others as secondaries for electrical power. The challenge is to control the mechanical outputs of torque and speed while independently regulating the electrical outputs of voltage and current. This thesis analyzes and demonstrates an approach that takes advantage of topological symmetries in multiphase systems to overcome this challenge. This method is applied, but not relegated to induction machines.
