A novel control strategy for electrolytic capacitor-less PMSM drive system

This paper presents a novel control strategy to reduce the DC-link voltage ripple for electrolytic capacitor-less PMSM drive system. By injecting the 3rd harmonic current into the driver system, the instantaneous power balance between the grid output power and the motor output power is achieved, so the DC-link voltage ripple is reduced obviously. For further improving the PMSM performance under DC-link voltage ripple, the repetitive control is introduced in the speed control loop of the space vector control. In addition, the input power factor can reach 0.95 and the harmonic of grid current are lower than the requirement of EN61000-3-2.
