摘要：A converter system for converting alternating current of variable frequency into alternating current of constant frequency is provided, having: a first converter electrically connected to a first set of turns of a generator; and at least a second converter electrically connected to a second set of turns of the generator, wherein the first converter in a first operating mode determines a first estimated rotor position of the generator, and performs driving operations of first power transistors, contained in the first converter, for converting the alternating current based on the first estimated rotor position, wherein the second converter in a first operating mode receives the first estimated rotor position of the generator from the first converter, and performs driving operations of second power transistors, contained in the second converter, for converting the alternating current based on the first estimated rotor position.

主权项：1. A converter system for converting alternating current of variable frequency into alternating current of constant frequency, wherein the converter system comprises: a first converter which can be electrically connected to a first set of turns of a generator; and at least a second converter which can be electrically connected to a second set of turns of the generator, wherein the first converter is designed, in a first operating mode, to determine a first estimated rotor position of the generator, andto perform driving operations of first power transistors, which are contained in the first converter, for converting the alternating current based on the first estimated rotor position, wherein the second converter is designed, in a first operating mode, to receive the first estimated rotor position of the generator from the first converter, andto perform driving operations of second power transistors, which are contained in the second converter, for converting the alternating current based on the first estimated rotor position.
