Novel variable voltage variable frequency electric drive

Large Engineering Systems Conference on Power Engineering, 2003, 2003
This paper provides a detailed description of the steady state performance of this system, based on a standard gas turbine prime mover. Economic considerations are discussed, as is dynamic performance and speed regulation. This topology would provide a definite advantage in reducing the amount of power electronic converter requirements, and eliminating
