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.
