<p>PURPOSE:To eliminate the interference of an apparent effective power and a reactive power by advancing in advance the phase of a primary crossing magnetic flux vector reference value in the amount corresponding to the delays of a detector, a current controller. CONSTITUTION:Vector dividers 12, 14 divide the outputs of a system angle frequency reference generator 7, a rotary angle frequency detector 9, a primary current vector detector 8. The delays w2 of current controllers 21-23 and delays thetaC of detectors 5, 7-9 are corrected for a primary crossing magnetic flux vector reference value phi1 to output a corrected primary crossing magnetic flux vector phi'1. A vector multiplier 13 outputs an exciting current reference vector i'0. A vector subtractor 16 calculates a secondary current vector reference value i2 on the basis of the outputs of the divider 14 and the multiplier 13 to apply it to a 2-phase/3-phase converter 17.</p> |
