Fault-Tolerant Operation of an Open-End Winding Five-Phase PMSM Drive with Inverter Faults [PDF]
, 2013 The authors would like to thank the ADEME for the funding of the MHYGALE project.Multi-phase machines are known for their fault-tolerant capability. However, star-connected machines have no fault tolerance to inverter switch short-circuit fault.

Orbifold Euler Characteristics for Dual Invertible Polynomials [PDF]
Moscow Mathematical Journal, 2012 To construct mirror symmetric Landau-Ginzburg models, P.Berglund, T.Hübsch and M.Henningson considered a pair $(f,G)$ consisting of an invertible polynomial $f$ and an abelian group $G$ of its symmetries together with a dual pair $(\widetilde{f}, \widetilde{G})$. Here we study the reduced orbifold Euler characteristics of the Milnor fibres of $f$ and $\

Control Strategies for Open-End Winding Drives Operating in the Flux-Weakening Region [PDF]
, 2013 This paper presents and compares control strategies for three-phase open-end winding drives operating in the flux-weakening region. A six-leg inverter with a single dc-link is associated with the machine in order to use a single energy source.

Dual 3-Phase Bridge Multilevel Inverters for AC Drives with Voltage Sag Ride-through Capability
Energies, 2019 One of the main power quality issues that can affect variable speed drives (VSDs) is the occurrence of voltage sags on their AC power supply. Voltage sags can affect the inverter nominal operation, leading to a malfunction of the AC motor.

Monodromy of dual invertible polynomials
, 2010 A generalization of Arnold's strange duality to invertible polynomials in three variables by the first author and A.Takahashi includes the following relation. For some invertible polynomials $f$ the Saito dual of the reduced monodromy zeta function of $f$ coincides with a formal "root" of the reduced monodromy zeta function of its Berglund-Hübsch ...
