Abstract

PURPOSE:To achieve highly accurate vector control, by modifying the setting value of secondary circuit time constant such that the deviation of actual secondary current obtained based on primary current from a secondary current command will be zero. CONSTITUTION:A vector controller 16 carries out vector control according to a secondary current command setting value and produces a primary current command i1. A secondary current operation unit 7 operates secondary current I2 from primary voltage (v1) and primary current (i1). The operated secondary current I2 is fed back as a basic operation signal for carrying out vector control to a vector controller 16 while simultaneously employed as a correction signal for secondary circuit time constant. Difference I2 between the secondary current command I2' and the operated secondary current I2 is obtained through a subtractor 23. The difference I2 is accumulated through an integtator 21 and outputted as a correction amount T2 for secondary circuit time constant.
