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 1):
A controller for a power convertor, the controller comprising:\n a torque command value calculation module configured to calculate a first torque command value to a power convertor based on a speed command value of a motor driven by the power convertor; a torque command limit module configured 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 defined by an upper limit torque value calculated by a predetermined calculation formula for upper limit torque command value calculation and a lower limit torque value obtained by multiplying the upper limit torque value by a predetermined negative coefficient or zero; a flux command generation module configured to generate a stator flux command value in accordance with a fundamental wave output frequency of output from the power convertor; and an output voltage calculation module configured to calculate an output voltage command value of the power convertor based on the second torque command value and the stator flux command value, wherein the torque command limit module calculates the upper limit torque value to be smaller as the fundamental wave output frequency increases at least in a speed region equal to or higher than a field weakening starting point.
