Abstract:
A controller for a power convertor includes: a torque command value calculation module to calculate a first torque command value to a power convertor; a torque command limit module to receive the first torque command value and generate a second torque command value obtained by correcting the first torque command value so that the first torque command value is limited to a torque limiter range. The torque command limit module sets a width between the upper limit torque value and the lower limit torque value of the torque limiter range to be smaller as a fundamental wave output frequency of the power convertor increases at least in a speed region equal to or higher than a field weakening starting point.

Claim (Index 2):
The controller for a power convertor according to  claim 1 , wherein\n the torque command limit module includes a first block configured to calculate the upper limit torque value in accordance with a predetermined first calculation formula for upper limit torque command value calculation when the fundamental wave output frequency belongs to a first speed region between the field weakening starting point and a boundary speed predetermined to be higher than the field weakening starting point, and the first calculation formula is a second-order polynomial including a second-order term and a first-order term of the stator flux command value.
