Abstract

In this letter, an optimal switching pattern-based asymmetric three-phase decoupled modulation strategy for six-phase inverter-fed dual three-phase PMSM drive is proposed to improve the steady-state performance, as well as maintain a low switching frequency. Therein, the equivalent voltage vectors for the decoupled voltage vectors in harmonic plane are established. An optimal switching pattern for asymmetric three-phase modulation strategy considering current harmonic suppression is proposed. Comparative studies are conducted to demonstrate the effectiveness of the proposed modulation strategy.
