Description
まず、本発明の実施例1に係るモータ制御装置について図面を用いて説明する。図4は、本発明の実施例1に係るモータ制御装置のブロック図である。本発明の実施例1に係るモータ制御装置101は、PWM整流器1と、平滑コンデンサ2と、直流電圧検出部3と、LCLフィルタ4と、動力遮断部5と、制御部6と、を有する。
次に、本発明の実施例2に係るモータ制御装置について説明する。実施例2に係るモータ制御装置102の構成は、図4に示した実施例1に係るモータ制御装置101と同様であって、PWM整流器1と、平滑コンデンサ2と、直流電圧検出部3と、LCLフィルタ4と、動力遮断部5と、制御部6と、を有する。実施例2に係るモータ制御装置102が実施例1に係るモータ制御装置101と異なっている点は、制御部6が、動力遮断部5により動力が遮断される前に、PWM整流器1を制御することにより、直流リンクの直流電圧を交流電源20の波高値まで下げておく点である。実施例2に係るモータ制御装置のその他の構成は、実施例1に係るモータ制御装置における構成と同様であるので、詳細な説明は省略する。
