Description
このような従来の電力変換装置は、短絡故障が発生していない正常時にもシャント抵抗にて電力損失が発生する。このため、電力変換装置における効率が低下する。また、電力損失による過熱を防止するために放熱対策の必要性が生じる。この結果、電力変換装置の大型化・コストアップに繋がる。また、短絡故障によって流れた短絡電流を検出した後に、その大電流を半導体スイッチで遮断する必要がある。このため、大電流の遮断時に、半導体スイッチの安全動作領域を逸脱して2次的な故障が発生する可能性がある。
図1は、本発明の実施の形態1における3相の電動発電機を用いた駆動発電システムの全体構成図である。この図1における駆動発電システムは、電力変換装置1と、その外部に接続されたバッテリ7、配線インダクタンス8、および3相の電動発電機に相当するモータジェネレータ9で構成されている。
先の実施の形態1では、1パルス通電方式として180度通電制御を行った際の短絡故障検出について説明した。これに対して、本実施の形態2では、1パルス通電方式として120度通電制御を行った際の短絡故障検出について説明する。すなわち、先の図1の構成において、通電角120度の1パルス通電制御を適用してモータジェネレータ9を駆動した場合の、短絡故障発生時を含む各部の動作波形について説明する。図3は、本発明の実施の形態2における120度通電制御時の各部の動作波形の説明図であり、各波形項目は、先の図2と同じである。
先の実施の形態1、2では、1パルス通電方式としてそれぞれ、180度通電制御、120度通電制御を行った際の短絡故障検出について説明した。これに対して、本実施の形態3では、1パルス通電方式の代わりに同期整流制御を行った際の短絡故障検出について説明する。すなわち、先の図1の構成において、モータジェネレータ9の発電モードにて同期整流制御を行った場合の、短絡発生時を含む各部の動作波形について説明する。図4は、本発明の実施の形態3における同期整流制御時の各部の動作波形の説明図であり、各波形項目は、先の図2と同じである。
