Novel electric drive with power-regenerating capability: modeling and simulation

Abstract

This paper provides a detailed modeling of the variable voltage variable frequency drive system (VVVF) proposed by previous research. The AC/DC converter performance at low speed is tested and propulsion drive startup has been evaluated. The ability of the drive to provide power regeneration has been investigated, and the simulations suggest that the VVVF drive would have the ability to support substantial levels of pulse loads.
