Abstract
Description
(サージ電圧の抑制)
サージ電圧の発生によってパワー半導体素子が破壊したり、サージ電圧に起因する電力変換装置の寄生容量両端の電圧変化からノイズ電流が発生し、車体へ流出するといった悪影響を及ぼすことが懸念される。また、後述の電力変換装置入力部より流出するノイズにも影響する。図4はサージ電圧を説明する図である。図4において、IGBT328のVceはコレクタ・エミッタ間電圧であり、Icはコレクタ電流である。パワーモジュール300の上アームIGBT328のコレクタ端子−エミッタ端子間に発生するサージ電圧△Vceは、次式(1)で表される。
なお、式(1)において、L2はコンデンサ端子563p(563n)とパワー側端子562p(562n)との間の寄生インダクタンス、Lpはパワーモジュール300の寄生インダクタンス、(di/dt)は上アームIGBT328のスイッチング時の電流変化である。
(電力変換装置入力部から流出するノイズの低減)
次に、図3,5を参照して、電力変換装置入力部より流出するノイズ低減方法について説明する。上述したサージ電圧の発生に伴い、導体564p、564nの電源側端子561p、561nの電圧Vbatに電圧変化が生じる。この電圧変化が、電力変換装置入力部より伝導ノイズ・放射ノイズとして流出することで、電源であるバッテリ136や周辺の電気回路へ悪影響を及ぼすことが懸念される。
(第1の例)
図6,7は、導体564p、564nの第1の例を示す図である。図6は、コンデンサモジュール500の斜視図である。一方、図7は、導体564pおよび導体564nの平面図を個別に図示したものである。導体564p,564nは板状の導体であって、ここでは厚さ方向に配置された幅広の表裏両面を主面と呼ぶことにする。
(第2の例)
図9〜11は、導体564p、564nの第2の例を示す図である。図9はコンデンサモジュール500の斜視図であり、図10は正面図である。また、図11は、コンデンサモジュール500を底面側から観た斜視図である。図6の場合と同様に、コンデンサモジュール500に設けられたコンデンサ514は、6つの側面を有する略直方体形状に構成されている。
(第3の例)
図12は、第3の例における導体564p、564nを示す図である。第3の例では、寄生インダクタンスL1,L2の大きさをL1>L2のように設定する方法として、導体断面積を異ならせるようにした。具体的には、コンデンサ端子563p、563nとコンデンサ端子560p、560nとの間の導体564p、564nの断面積(C2−C2断面)を、コンデンサ端子563p、563nとパワー側端子562p,562nとの間の導体564p、564nの断面積(C1−C1断面)よりも小さく設定した。断面積の大きさは、幅W1,W2や導体厚さを変更することで調整する。
