Description
請求項5記載の電力変換装置によれば、絶縁コンバータ部をDABコンバータとする。
以下、第1実施形態について説明する。図1は、本実施形態の電力変換システムであるV2Hシステムの構成を示す。V2Hシステム1は、系統電力線2、太陽光発電部である太陽光パネル3、蓄電部である蓄電池4の間で電力を変換して伝送するものである。尚、蓄電池4については、電気自動車に搭載される走行駆動用モータに駆動用電源供給するバッテリでも、電気自動車に搭載されないバッテリでも良い。
1/{2π×(Lr1+Lm1)×C1}<f<1/(2π×Lr1×C1)
そして、低下させるバス電圧に基いて算出したスイッチング周波数をf’dとすると、周波数f’dと周波数[1/{2π×(Lr1+Lm1)×C1}]とを比較し、より高い値を選択する。
1/{2π×(Lr2+Lm2)×C2}<f<1/(2π×Lr2×C2)
そして、低下させるバス電圧に基いて算出したスイッチング周波数をf’cとすると、周波数f’cと周波数[1/{2π×(Lr2+Lm2)×C2}]とを比較し、より高い値を選択する。
以下、第1実施形態と同一部分には同一符号を付して説明を省略し、異なる部分について説明する。図5に示す第2実施形態のV2Hシステム31において、DC/DC変換回路32は、第1実施形態の電力変換装置7に相当するが、図2に示す処理は行わず、常に通常モードで動作する構成である。そして、AC/DC変換回路5と、DC/DC変換回路6との間に、もう1つのDC/DC変換回路33を追加している。DC/DC変換回路33は、単方向変換で降圧動作を行う構成である。
スイッチング素子は、NチャネルMOSFETに限ることなく、電源側にPチャネルMOSFETを使用したり、IGBTを用いても良い。
バス電圧やスイッチング周波数、動作モードを切り替える際の閾値については、個別の設計に応じて適宜設定すれば良い。
