TL;DR: Compared with the conventional nearest-three virtual space vector (NTV2) technique, the proposed modulation scheme employs three adjacent medium vectors to synthesize a new medium vector and two pairs of large vectors to compose new small vectors to achieve balanced capacitor voltage and reduced CMV at the same time.

TL;DR: A virtual space vector based overmodulation algorithm is presented for three-level neutral-point (NP) clamped converters in high-speed aerospace motor drives with the proposed inscribed polygonal-boundary compression technique, which brings an opportunity for the operation of the studied aircraft electric starter/generator systems easily extending from the linear modulation range into the overmodulated region.

TL;DR: In this paper, a set of simple, generic, and fast tuning rules were derived that guarantee fast dynamic performance with reasonable stability margins, and the effects of model uncertainties on these developed rules have been analyzed and reported.

TL;DR: A proposed modulation scheme is presented based on virtual-space vector concept to achieve both NP voltage balancing and lower CMV in ESG system and g-h coordinate is used to overcome excessive computational burden which is common in high-frequency power converter applications.

TL;DR: A simplified virtual space vector PWM (VSVPWM) by using g-h coordinate for three-level neutral-point clamped power converter applications will significantly simplify calculation workload and thus allowing for being used in higher switching frequency application areas.
