Abstract :
The paper is dedicated to the development of the novel energy saving speed adjustable AC drive with two-stage direct frequency converter (TSDFC) which provides sinusoidal input/output currents and recuperation. Paper describes the two-step control strategy based on the analysis of the TSDFC properties and the problem decomposition. This strategy was realised in the 7.5 kW laboratory setup and first in the world 110 kW experimental-industrial induction motor drive. The results of experimental study are presented.
