Description
電力変換を行う同期整流型のコンバータ部と、
前記コンバータ部の出力電圧に比例する電圧を検出する電圧検出回路と、
前記電圧検出回路により検出される検出電圧と基準電圧とを比較し、前記検出電圧が一定になるよう前記コンバータ部の動作を制御するコンバータ制御部と、
外部から入力される目標電圧指令値が前記出力電圧の電圧値よりも低い場合、前記基準電圧の電圧値を、前記検出電圧の電圧値と等しくする指令処理部と、を備える。
前記指令処理部が、外部から入力される目標電圧指令値が前記出力電圧の電圧値よりも低い状態が予め設定された基準時間以上継続した場合、前記コンバータ制御部に前記コンバータ部の動作を停止させるための停止信号を、前記コンバータ制御部へ出力する、ものであってもよい。
前記指令処理部が、前記基準電圧の電圧値を、前記検出電圧の電圧値と等しくした後において、外部から入力される目標電圧指令値が前記出力電圧の電圧値よりも低い場合、前記コンバータ部の動作を停止させるための停止信号を、前記コンバータ制御部へ出力する、ものであってもよい。
第1蓄電装置を充電するスイッチング電源装置であって、
第2蓄電装置と、
前記第2蓄電装置が入力側に接続された上記同期整流型DC−DCコンバータと、を備え、
前記コンバータ部は、前記第2蓄電装置から供給される電力を変換して前記第1蓄電装置へ供給する。
以下、本発明の実施の形態について図面を参照して詳細に説明する。本実施の形態に係る同期整流型DC−DCコンバータは、例えば第1蓄電装置と第2蓄電装置の間に接続され、第2蓄電装置から供給される電力を変換して第1蓄電装置へ供給する。この同期整流型DC−DCコンバータは、出力電圧が基準電圧と等しい電圧で一定となるように制御するコンバータ制御部と、外部から入力される目標電圧指令値に応じて基準電圧を設定する指令処理部と、を備える。そして、この同期整流型DC−DCコンバータは、目標電圧指令値が出力電圧値よりも低い場合、基準電圧を、電圧検出回路により検出された検出電圧に等しくすることにより、第1蓄電装置から第2蓄電装置への逆流を抑制する。
本実施の形態に係る同期整流型DC−DCコンバータは、目標電圧指令値が出力電圧値よりも低い場合、コンバータ部の動作を停止させることにより、他方の蓄電装置から一方の蓄電装置への逆流を抑制する。
本実施の形態に係る同期整流型DC−DCコンバータは、目標電圧指令値が出力電圧値よりも低い場合、まず、コンバータ制御部2011へ入力される基準電圧を強制的にコンバータ部10の出力電圧に比例する電圧に設定する。その後、同期整流型DC−DCコンバータは、目標電圧指令値が出力電圧値よりも低い状態が予め設定された基準時間以上継続した場合、コンバータ部の動作を停止させる。
