Abstract
PURPOSE:To prevent the saturation of the adjuster and to perform the stable phase control to the lower frequency by adding a multiplier, to which the control deviation and the inverter output frequency can be added, to an angle adjuster, and giving the variable factor to the control deviation. CONSTITUTION:In order to control the phase of the output current of voltage of the inverter, the established value obtained from a vector analizer 11 and a divider 14 is compared with the actual value obtained from voltage and current detectors 16 and 17, a magnetic flux operator 18, a vector circuit 19, and a divider 20, and the deviation is added to the angle adjuster 15, where the integrating operation is performed. At this time, a multiplier 150 is added to the front stage of the angle adjuster 15. By multiplying a factor K which is proportional to the inverter output frequency to said deviation, the variable factor is given. By decreasing said factor at the low frequency region, the saturation of the angle adjuster 15 is prevented over the broad frequency range, and the stable operation can be performed.
