초록

Wound-field synchronous motors are currently being heavily researched. These devices are advantageous in that they can flexibly cope with a high-speed control region and their material costs are lower than those of a permanent magnet-type synchronous motor. However, one disadvantage is that mechanical defects occur over long operation, and the control performance and output density become insufficient. Controlling the design of WFSMs by considering volume and weight limitations causes many harmonic components in the current of the stator and field, which are reflected as noise and loss. As a result, harmonics are generated in the current of the DC link capacitor in the inverter, and the lifetime of the capacitor is shortened according to the rms value of the ripple component. In this paper, we propose a vector-control algorithm that compensates the mutual interference components and a vector-control algorithm with high-frequency current injection to reduce the harmonic components of the motor.
