| description | To provide a power converter control system which can suppress an increase of a temperature of a permanent magnet of a rotary electric machine while suppressing noise and vibration accompanied with a switchover of a carrier frequency, a motor system, and a complex system.SOLUTION: A power converter control system has a power converter supplying power to a rotary electric machine, and a control device controlling the power converter. The control device controls the power converter by a synchronization control in which a carrier frequency of the power converter is proportional to a rotation frequency of the rotary electric machine when a temperature of a permanent magnet which the rotary electric machine has is higher than a predetermined threshold value, and controls the power converter by a non-synchronization control in which the carrier frequency of the power converter is not proportional to the rotation frequency of the rotary electric machine when the temperature of the permanent magnet is equal to or less than the predetermined threshold value.SELECTED DRAWING: Figure 5
【課題】キャリア周波数の切り替えに伴う騒音および振動を抑制しつつ、回転電機の永久磁石の温度の上昇を抑制することができる電力変換装置制御システム、モータシステムおよび複合システムを提供する。【解決手段】電力変換装置制御システムは、回転電機に電力を供給する電力変換装置と、前記電力変換装置を制御する制御装置とを備え、前記制御装置は、前記回転電機が有する永久磁石の温度が所定の閾値よりも高い場合に、前記電力変換装置のキャリア周波数が前記回転電機の回転数に比例する同期制御によって前記電力変換装置を制御し、前記永久磁石の温度が前記所定の閾値以下の場合に、前記電力変換装置のキャリア周波数が前記回転電機の回転数に比例しない非同期制御によって前記電力変換装置を制御する。【選択図】図５ |
