Abstract
【解決手段】インバータIV1、コンバータCVおよびインバータIV2を構成する上側アームのスイッチング素子と下側アームのスイッチング素子とは、基板30に対して2列に配置され、その制御端子(ケルビンエミッタ電極KE、センス端子ST、ゲートG)が基板30に差し込まれている。これら2列の間には、フェール用フォトカプラPCfが配置されている。インバータIV1に対応するフェール用フォトカプラPCfは、隣接するもの同士で直列接続され、各列の端部が接続されることでU字型の配線構造を有し、その端部がマイコン20に接続されている。
【選択図】 図3
Description
<その他の実施形態>
なお、上記実施形態は、以下のように変更して実施してもよい。
フェール用絶縁手段としては、フェール用フォトカプラPCfに限らず、たとえばフォトMOSリレーであってもよい。また、光絶縁素子に限らず、たとえばトランス等の磁気絶縁素子であってもよい。
操作用絶縁手段としては、駆動用フォトカプラPCgに限らず、たとえばフォトMOSリレーであってもよい。また、光絶縁素子に限らず、たとえばトランス等の磁気絶縁素子であってもよい。
先の図3において、フェール用フォトカプラPCfの2次側の全てを直列接続することで、全フェール信号FLをシリアルラインを介してマイコン20に出力してもよい。
高電位側のスイッチング素子Swpと低電位側のスイッチング素子Swnとを2列に配置する手法としては、高電位側のスイッチング素子Swpからなる列と低電位側のスイッチング素子Swnからなる列との2列とするものに限らない。たとえば、高電位側のスイッチング素子Swpと低電位側のスイッチング素子Swnとからなる各直列接続体毎に、これらを構成する高電位側のスイッチング素子Swpと低電位側のスイッチング素子Swnとを、2つの列の同一行に割り振るものであってもよい。もっとも同一行に割り振るものに限らない。さらに、1の直列接続体を構成する高電位側のスイッチング素子Swpと低電位側のスイッチング素子Swnとを、同一列に配置するものであってもよい。
パワーカードPWCの配置としては、先の図4に例示したものに限らない。たとえば、双方のパワーカードPWCについて、制御端子が配置されている側を内側としたり、外側としたりしてもよい。これらの場合、高電位側のパワーカードPWCと低電位側のパワーカードPWCとで、制御端子が偏って配置されている側が相違するようにするなら、基板30の両側に高電位側の配線および低電位側の配線を配置した場合の接続が容易となる。
スイッチング素子Sw#(#=p,n)としては、1のスイッチング素子毎にパッケージ化されているものに限らない。たとえば高電位側のスイッチング素子Swpおよび低電位側のスイッチング素子Swnの直列接続体で1パッケージとされているものであってもよい。
直流交流変換回路としては、駆動輪に機械的に連結される回転機に接続されるものに限らない。たとえば、高電圧バッテリ12を直接の電源とする空調装置のコンプレッサに内蔵される回転機等であってもよい。
・スイッチング素子Sw#の冷却手法としては、水冷に限らず、空冷であってもよい。
