Control strategy for a matrix converter with a generator and a motor

This paper proposes the stability control method for the input current of the matrix converter considering the synchronous reactance of a generator and a motor drive. When the stability control uses the input current feedback with a vector control for the generator side, the oscillation in the input filter can be suppressed. However, the output current oscillation occurs when the high response output current control at the same time due to no energy buffer in the matrix converter. The proposed stability control is the output current control including a damping factor for the input filter oscillation. This proposed method can achieve a stable operation for the generator side and the motor drive at the same time. In this paper, root placement is used to discuss the stability of the proposed controls. In addition, this paper confirms the validity of the proposed controls in a matrix converter with a generator and a motor by demonstrating the simulation and experimental results.
