Description
なお、抵抗R1はレシーバCMPの非反転入力端子と制御電源Vcc間に接続され、抵抗R2はレシーバCMPの非反転入力端子と第2の接地電位点GND2間に接続され、抵抗R3はレシーバCMPの反転入力端子と制御電源Vcc間に接続され、抵抗R4はレシーバCMPの反転入力端子と第2の接地電位点GND2間に接続されている。また、第2の接地電位点GND2の電位は、通常、駆動されるIGBTのエミッタの電位になる。このため、一般に、ハイサイドIGBTに対するゲート駆動回路では、第2の接地電位点GND2は主電源の接地電位に対しフローティングとなる。
本発明のゲート駆動回路において、前記第3の層には、前記正側の信号出力端子と前記第1の接続部とに接続される第4の接続部と、前記負側の信号出力端子と前記第2の接続部とに接続される第5の接続部と、が設けられたことを特徴とする。
本発明のゲート駆動回路において、前記正側の信号入力端子、前記負側の信号入力端子、前記正側の信号出力端子、前記負側の信号出力端子、及び前記接地端子は、前記第1の層における前記絶縁層と反対側となる主面の側に配置されたことを特徴とする。
本発明のゲート駆動回路において、前記一次巻線の他端は、前記負側の信号入力端子を介して前記第1の接地電位点と接続されたことを特徴とする。
本発明のゲート駆動回路は、前記二次巻線の他端にインピーダンス整合用抵抗が接続されたことを特徴とする。
モータドライブ用IGBTのゲート駆動回路において、通常、パルストランスTの二次側における第2の接地電位点GND2はパルストランスTの一次側における第1の接地電位点GND1に対しフローティングになっており、更に、ハイサイドIGBT用のゲート駆動回路では、第2の接地電位点GND2が主電源の接地電位に対しフローティングとなっている。したがって、ゲート駆動信号は、上記のノイズ電流ixにより第2の接地電位点GND2の電位変動の影響を受けやすいという問題があった。通常、パルストランスTの一次巻線N1と二次巻線N2との間には寄生容量Cxが存在するため、パルストランスTの一次側、二次側のどちらにもノイズ電流ixが流れる。特に、差動受端間にノイズ電流ixが流れ込んだ場合、差動増幅器(レシーバCMP)の電圧が変動し、回路的な誤動作を生じさせる。本発明は、上記の寄生容量Cxに対して静電シールドを施し、回路的に問題の無い別経路(静電シールド板5から第2の接地電位点GND2へ直接)にノイズ電流を流すように構成される。
また、以上の「発明を実施するための形態」として説明した例は、一例を示したものであって、本発明の主旨を逸脱しない範囲で変更することができることは勿論である。
