Description
Claims (3)
- 三相交流電源の電圧をスイッチングにより昇圧および直流変換しスイッチング停止により全波整流する三相PWMコンバータと、
前記三相PWMコンバータの出力電圧を交流電圧に変換しその交流電圧をモータの駆動用として出力するインバータと、
前記三相PWMコンバータから流出する高調波電流を検出する電流検出部と、
運転開始から前記電流検出部の検出結果が制限値に達しないうちは前記三相PWMコンバータのスイッチングを停止し、その後、前記電流検出部の検出結果が前記制限値に達した場合に、第1電圧値を昇圧の目標値として前記三相PWMコンバータのスイッチング動作を開始し同三相PWMコンバータの出力電圧が前記第1電圧値まで上昇したところで同三相PWMコンバータの昇圧レベルを保つ制御部と、
を備え、
前記第1電圧値は、前記三相PWMコンバータが無負荷状態で全波整流する場合にその三相PWMコンバータから出力される電圧の近傍の値である、
ことを特徴とするモータ駆動装置。 - 前記制限値を可変設定する制限値設定手段、をさらに備えることを特徴とする請求項1記載のモータ駆動装置。
- 前記第1電圧値は、三相交流電源の電圧が200Vの場合に280Vであることを特徴とする請求項1記載のモータ駆動装置。
