摘要

Aiming to obtain high efficiency of electrical drives for near-space vehicle, we proposed a novel three-level inverter DTC method for PMSM, to suppress current harmonic components and toque ripples. Sections 1 and 2 of the full paper explained the proposed method in detail. Their core consists of: "In order to bypass the implementing complexity of space vector PWM (SVPWM) for three-level inverter, we have presented a relatively simple calculation method which is easy to implement with field programmable gate arrays through choosing proper large and small voltage sectors and through using the principle of symmetry and normalization. The reference voltage was presented under polar coordinates and vector phase was used to condense the decisions of sectors. The three-level inverter and traditional two-level inverter DTC simulation models were constructed respectively with Matlab/Simulink for comparative analysis". The simulation results, presented in Figs. 6 and 7, have shown preliminarily the validity of our proposed method in suppressing efficiently current harmonics and torque pulses.
