Abstract: Motor drivers employ film capacitors instead of the conventional electrolytic capacitors to achieve better reliability and smaller volume. However, these drivers have an instability problem because of a resonance between the small dc-link capacitance and grid side line inductance. In order to solve the problem, this paper proposes an active damping method using d-axis current injection. Since the injected current acts as damping impedance, the proposed method suppress dc-link voltage fluctuations. The relationship between the injected current and the virtual damping impedance is mathematically analyzed. Moreover, the proposed method is able to reduce the torque ripple caused by the injected current in spite of system loss increase. The increased loss also can be minimized by characteristics of the motor. The feasibility of the proposed method is proved by several experimental results.
