Abstract
The multiphase and multilevel motor drives have attracted more and more attention during the last decade since they offered advantages of high-power rating, lower voltage and current stresses in semiconductor switches, higher fault-tolerant ability, compared to the conventional two-level three-phase drives. This paper presents a model predictive current control (MPC) for a T-type three-level inverters fed dual three-phase permanent magnet synchronous motor (PMSM) drives. The key is to propose new space voltage vector synthesis method for voltage vector candidates in MPC scheme of the T-type three-level inverters fed dual three-phase PMSM drives. The proposed scheme can alleviate the computation burden of MPC and suppress the current harmonics induced from inherent property of dual three-phase PMSM. The experimental results are given to verify the validation of the proposed scheme.
