| This article proposes an 18-switch five-level inverter topology for induction motor (IM) drives, enabling an extended linear modulation range (LMR) till full base speed. The power circuit consists of a conventional NPC three-level inverter and a standard two-level inverter feeding the opposite phase winding ends of an open-ended winding IM. The proposed inverter achieves a voltage space vector radius of 0.955 Vdc and a maximum peak fundamental phase voltage of 0.637 Vdc in its LMR compared to a conventional five-level inverter with the corresponding figures of 0.866 and 0.577 Vdc , respectively. This improvement arises from the fact that in the overmodulation region spanning from 0.577 to 0.637 Vdc , the standard five-level inverter operates in a six-step mode, resulting in the voltage space vector trace a hexagonal path producing a lower-order harmonic-rich phase voltage. The proposed power circuit effectively addresses this issue by ensuring a circular locus for the voltage space vector up to a radius of 0.955 Vdc resulting in a maximum peak fundamental voltage of 0.637 Vdc . Consequently, it extends the linear speed range of the motor to the full base speed without lower-order harmonic problems. |
