This paper proposes new vector controllers in the D-module for controlling current of three-phase systems, which have no vector-rotators in current control loop. Conventional standard vector controller controls current of three-phase systems in rotational reference frame and a couple of vectorrotators are indispensable in the loop. Vector rotators that perform sinusoidal operations on current must be realized in discrete-time manner, and sampling of current for the discrete-time processing restricts attainable bandwidth of the current control loop. Broader bandwidth of the loop is desired for both quick response and disturbance suppression. The proposed vector controllers in the D-module are so simple that no vector rotators in the loop are required, and can be realized in continuous-time manner due to its simplicity. Furthermore, under the same bandwidth of the currentloop, the proposed one can show the equivalent performance to conventional standard vector controller having vector-rotators in the loop. These features allow broader bandwidth of the loop and better current control performance than the conventional vector controller. Two new vector controllers in the D-module are presented and their usefulness is examined and confirmed through numerical experiments. © 2002, The Institute of Electrical Engineers of Japan.
