Description
クランプキャパシタが満充電又は満充電に近づいたことを検知した後は、高電圧側スイッチング回路のスイッチングデューティ比は、電流逆流を発生させないために選択すべきスイッチングデューティ比に相当する。クランプキャパシタの充電はほぼ完了しているため、スイッチング素子に過剰な電圧が印加されることはない。
図1は、本発明の実施例1による電力変換装置であるDC−DCコンバータ400の回路図である。このDC−DCコンバータ400は、例えば、車両の搭載される電力変換装置である。
ステップA20において、DC−DCコンバータ400のスイッチング動作が停止状態にあるか否かを判断し、動作停止状態にあると判断した場合はステップA30に遷移する。ステップA20において、動作停止状態ではないと判断した場合はステップA50に遷移する。
ステップA40において、ステップA20、A30の分岐経路によりステップA40に到達したときは、スイッチング動作が停止状態にあり、かつスイッチング開始要求を受信した状態にある。この状態において、時間カウンタ(図示せず)をリセットし、カウントを開始する。
上記式(1)を用いて積分項errkiを算出後、ステップB170へ遷移する。
ズッテプB180にて、上記式(2)を用いて積分項errkiを算出後、ステップB190へ遷移する。
ステップB190にて、上記式(3)を用いてDuty算出完了後、ステップB200へ遷移する。
次に、スイッチング信号生成部335は、MOSFET220のON/OFF信号S40を生成する。ON/OFF信号S40は、ON/OFF信号S30がONとなっている期間にOFFとなり、ON/OFF信号S30がOFFとなっている期間にONとなるように生成する。
次に、本発明の実施例2について説明する。
次に、本発明の実施例3について、説明する。
