Description
上記実施形態では、ヒートシンク(53)側から検出回路(60)側へ向かう電磁波を電磁遮蔽材(70)によって遮蔽している。これにより、電磁波の影響により検出回路(60)にノイズが重畳してしまうのを防止でき、検出回路(60)での誤検出を防止できる。従って、第2制御部(12)では、検出回路(60)で検出した電流値に基づいてモータ(M)の回転速度等を正確に調節でき、且つ検出回路(60)で検出した電圧値に基づいてモータ(M)の適正な保護制御を行うことができる。

51 第1パワーモジュール(スイッチング素子)
52 第2パワーモジュール(スイッチング素子)
53 ヒートシンク
60 検出回路(電流検出回路、電圧検出回路)
