Description
実施の形態1.
図1は、実施の形態1のトランスファーモールド型IPMの外形を表わす図である。
3相誘導モータMTは、位相の異なる3相の電圧により駆動するように構成されている。具体的に、3相誘導モータMTでは、位相が120度ずれたU相、V相、W相と呼ばれる3相交流を利用して導体であるロータRTの回りに回転磁界を発生させる。
3相インバータIVは、正の電圧線PLと3相誘導モータMTの各相(U相、V相、W相)の端子との間にIGBT4UU,4UV,4UWとFWD5UU,5UV,5UWが逆並列に接続され、かつ、3相誘導モータMTの各相の端子と負の電圧線NLとの間にIGBT4LU,4LV,4LWとFWD5LU,5LV,5LWが逆並列に接続されている。
図5は、実施の形態2のトランスファーモールド型IPMのレイアウトを表わす図である。
X方向において、左側からRC−IGBT10UU,10UV,10UW,10LU,10LV,10LWの順に配置される。これらの6つのRC−IGBTは、X方向において千鳥状に配置される。すなわち、Y方向において、左端のRC−IGBT10UUが第1の辺L1に近い位置に配置される。RC−IGBT10UUに隣接するRC−IGBT10UVが第2の辺L2に近い位置に配置される。RC−IGBT10UVに隣接するRC−IGBT10UWが第1の辺L1に近い位置に配置される。RC−IGBT10UWに隣接するRC−IGBT10LUが第2の辺L2に近い位置に配置される。RC−IGBT10LUに隣接するRC−IGBT10LVが第1の辺L1に近い位置に配置される。RC−IGBT10LVに隣接するRC−IGBT10LWが第2の辺L2に近い位置に配置される。
図6は、実施の形態3のトランスファーモールド型IPMのレイアウトを表わす図である。
領域RU内に、X方向において、左側からRC−IGBT10UU,10UV,10UWの順に階段状に配置される。すなわち、3つのRC−IGBTのうち、領域RUのX方向の一端に近い位置のRC−IGBT10UUは、Y方向において第2の辺L2よりも第1の辺L1に近い位置に配置される。領域RUのX方向の他端に近い位置のRC−IGBT10UWは、Y方向において第1の辺L1よりも第2の辺L2に近い位置に配置される。X方向においてRC−IGBT10UUの位置とRC−IGBT10UWの位置の間に位置するRC−IGBT10UVは、Y方向においてRC−IGBT10UUの位置とRC−IGBT10UWの位置の間の位置に配置される。
図7は、実施の形態4におけるトランスファーモールド型IPMに含まれる構成を表わす図である。
