This paper presents indirect-matrix- converter (IMC) for permanentmagnet synchronous-motor (PMSM) drives using improved torque predictive control (TPC). The IMC does not require capacitors in the DC-link, which makes it possible to reduce the volume of system unlike typical system of the AC-DC-AC power conversion. The IMC has advantages which are sinusoidal waveform in input-output current and high-power density. Therefore, researches in the IMC for PMSM drives using various torque control methods have been actively studied. In this paper, the IMC for the PMSM drives using the improved TPC is proposed. The ripple component of the torque of the PMSM is declined by the proposed method. also, the dynamic torque response is improved compared with the conventional torque control methods. The performance of the proposed method is verified by the results of the PSIM simulation tool.
