Description
Nine-switch Inverters (NSIs) have been proposed to accommodate the independent control of dual AC motors or in six-phase drives. This topology reduces the number of active switches by 25% compared with conventional Voltage Source Inverter (VSI). However, it has a main conceptual shortcoming of voltage gain limitations. The voltage gains of both outputs are low, and their values depend on the phase angle between the two three-phase voltage output sets. This paper introduces a Quasi-Z Source NSI (QZS-NSI) topology to overcome voltage gains shortcomings of NSIs. Although a body of research for conventional three-phase QZS-VSI has been undertaken, corresponding discussions for all the impedance network based NSI are still scarce and complicated. This paper proposes a simple carrier-based PWM approach to modulate the QZS-NSI in both common-frequency and different-frequency modes of …
