Abstract

A dual two-level voltage source inverter (VSI) fed open-end winding induction motor drive with isolated dc sources is more convenient for electric vehicle applications. For satisfactory operation of the drive, uniform state-of-charge (SOC) distribution is required whch can be achieved by the balanced power flow from each of the isolated sources. Model predictive direct torque control (MPDTC) cannot achieve such performance because it only considers torque and stator flux control without addressing dc-link power management. A two-stage MPDTC scheme is proposed to balance the SOC of batteries by proper selection of the inverter switching frequency. Also proposed MPDTC scheme is free from weighting factor tuning and uses a ranking method to predict the optimal voltage vectors. Simulation and experimental validation for HFET and a portion of the FTP75 driving cycle show the efficacy of the proposed system with proper battery SOC control.
