Abstract

A high-speed induction motor and soft-switching electronic drive are selected to transfer energy between a flywheel and the other power components of prototype hybrid locomotive power system. The motor-generator operates in direct coupling at 14,000 rpm (233 Hz) with the composite flywheel. The motor drive rating is 2 MW (2600 hp) over the operating frequency range of 125 to 250 Hz. The power-frequency range and harmonic heating considerations have lead to a auxiliary resonant commutation pole (ARCP) soft-switching design. The drive and motor have been tested over the full speed range. Unique requirements of energy storage and transfer are also presented.
