Abstract
Description
図1は、本実施形態に係る電源システムSを搭載する車両Vの構成を示す図である。なお本実施形態では、車両Vとして、2つの電源とこれら電源の間に設けられた電圧変換器を備える所謂電気自動車を例に説明するが、本発明はこれに限るものではない。本発明に係る電源システムは、電気自動車に限らず、ハイブリッド車両や燃料電池自動車等、2つ以上の電源とこれら電源の間に設けられた電圧変換器とを備えるものであれば、どのような車両にも適用可能である。
(1)電源システムSでは、VCU3の起動時には、上アーム32のトランジスタQ2をオフにした状態で下アーム31のトランジスタQ1のデューティ比γ1を漸増させる起動時制御を行った後、上アーム32のトランジスタQ2及び下アーム31のトランジスタQ1を相補的に駆動する通常制御を行う。ここで起動時制御を行っている間は、上アーム32のトランジスタQ2はオフに維持されるため、2次側電圧V2が1次側電圧V1より高い場合であっても、第2電源2側から第1電源1側へ向かう突入電流の発生を抑制できる。電源システムSでは、起動時制御によって下アーム31のデューティ比γ1を漸増させる過程において、電流センサ35によって検出されるリアクトル電流ILの値を用いて、実行中の起動時制御を終了し通常制御に移行するか或いは実行中の起動時制御を継続するかを判定する。これにより電源システムSでは、その時の1次側電圧V1と2次側電圧V2の差に応じた適切なタイミングで、すなわち起動時制御の下で下アーム31のデューティ比γ1を上記電圧の差に応じた適切な大きさまで増加させた状態で起動時制御を終了し通常制御に移行することができるので、通常制御への移行時における突入電流の発生を抑制できる。また電源システムSでは、電流センサ35によって検出されるリアクトル電流ILの値を用いることにより、電圧V1,V2の差を用いて閾値を調整したりすることなくその都度適切なタイミングで起動時制御の終了時期を決定できる。
