Title: Controller for converter which obtains direct current from multiphase alternating current
Inventor: TANAKA MASATSUGU
IPC: H02M7/12
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To ensure following-up capability and further a low distortion factor in control on a pulse width control converter, by determining the switching timing of an alternating current controller so that the evaluation function for alternating current distortion produced in one cycle is minimized. SOLUTION: A three-phase alternating current is converted through a d-q converter 12 to obtain an active alternating current id and a reactive alternating current iq. Two switching vectors are sequentially selected in one control cycle T in order that the active alternating current and the reactive alternating current agree with an active alternating current command value id* and a reactive alternating current command value iq*, respectively. Thereby a semiconductor switching element which acts as a converter to switch from the first switching vector to the second switching vector is controlled with appropriate timing α. At this time, distortion produced in one control cycle is taken as evaluation factor for determining the timing of switching, and the switching of the vectors is determined so that the evaluation factor is minimized.  As a result, since the first vector is switched to the second vector with the determined timing, the following-up capability is not degraded.
