Abstract
Description
各々が、2つの上記第一抵抗の間にて第一ノードとの第一接続を有している電気的なフィルタであって、各々が、第二抵抗および上記第二抵抗に接続されている電荷蓄積装置
を備えている電気的なフィルタを更に備えている動力電池システム、例えば燃料電池システムが提供される。上記抵抗は、抵抗、抵抗回路、またはダイオードが接続されたトランジスタのような他のタイプの抵抗であってもよい。上記抵抗は、シャント抵抗網において接続されている。他の実施形態において、各々の電気的なフィルタは、隣接している電気的なフィルタとの第二接続を介しても接続されている。各々の電気的なフィルタの隣接している電気的なフィルタとの接続は、各々の電気的なフィルタが各々の動力電池、例えば燃料電池に接続されているので、個別に電圧を供給することなく上記燃料電池システムの電気的なフィルタを作動させる。これより、結果的に各々の電気的なフィルタに従って1つのスイッチのみが必要となり、これにより、上記燃料電池システムは簡素で安価なものとなる。
