TL;DR: In this article, a peak voltage controller detects the peak voltage of a voltage command and outputs an adjustment command to instruct an amplitude adjuster 15 to suppress an amplitude when the output voltage is about to get over a value preset on the basis of the maximum output voltage or the maximum modulation percentage of the inverter.

Abstract: PROBLEM TO BE SOLVED: To adjust a torque control output according to the output voltage of an inverter. SOLUTION: This device has a peak voltage controller 18 which detects the peak voltage of a voltage command and outputs an adjustment command to instruct an amplitude adjuster 15 to suppress an amplitude when the peak voltage is about to get over a value preset on the basis of the maximum output voltage or the maximum modulation percentage of the inverter, and an amplitude adjuster 15 which lowers gains by performing, for example, the processing of removing a certain proportion of a value from an integrated value or the like, in answer to the supply of an adjustment command.
