    Abstract

    Using a small DC-link capacitor instead of the bulky electrolytic capacitor or power factor correction (PFC) circuit is an attractive solution to increase the lifetime for electric drive applications. While these drives are fed from a weak grid, a resonance will appear between the line side impedance and the DC-link capacitor. Because of this resonance, total harmonic distortion (THD) of the line current increases and may lead to some application problems based on the AC line harmonic standards. This paper proposes a new model predictive control (MPC) method for a three-phase diode rectifier system with a small DC-link capacitor to drive a permanent magnet synchronous motor (PMSM). The main function consists of effective factors to suppress the harmonics in grid-side current and current control for PMSM. Employing the proposed cost function leads to a reduction in grid-side current THD and a smoother current in the output of the diode rectifier. The effectiveness of the proposed method is verified through MATLAB software.
