摘要：

In the conventional AC-excited synchronous machine operated with mains excitation [1,2],the commutation conditions in the machine-side thyristor converter do not allow the drive to be notably overloaded. In addition operation with field weakening and full four-quadrant operation are not possible due to the principle. If on the other hand the AC-excited synchronous machine is excited by a small insulated gate bipolar transistor inverter (IGBT), then the commutation conditions in the machine-side thyristor converter can be improved with the control system presented here. Therefore a considerable overload capability and afield weakening range of 1:2 and more can be realized with the AC-excited synchronous machine. Areas of application previously excluded are thus opened up to the AC-excited synchronous machine.
