Abstract
Description
前記電源部は、前記第1の電池を前記一方の電池として選択する第1の態様と、前記第2の電池を前記一方の電池として選択する第2の態様とを切り替えるスイッチ群を有することを特徴とする電源システムを提供する。
電池部303の低電位側出力端子VOLから取り出された電力は、DC−DCコンバータ制御器302、スイッチ201、207、チョークコイル202、コンデンサ203により構成された第2の降圧型DC−DCコンバータにより降圧され、第2出力として出力2端子から出力される。従って、出力2端子に設定可能な最高電圧は低電位側出力端子VOLの電圧となる。
さらに、DC−DCコンバータ制御器302は、電池部制御信号を生成し、電池部303の電池部制御信号端子(CR)に入力する。電池部制御信号は、スイッチ101又はスイッチ201がオン状態となるタイミング情報や、これらスイッチのオン−オフ間隔の長さを示す情報を含む。スイッチ101又はスイッチ201がオンのとき、電池部303から電力が取り出されるが、オフの時には電池部303は、出力する必要はないので、この期間で電池部303の構成変更や充電量の監視処理を行うことができる。
電池部303の低電位側出力端子VOLから取り出された電力は、スイッチ502を経て、第2の降圧型DC−DCコンバータであるリニアレギュレータ504により降圧され、第2出力として出力2端子から出力される。従って、出力2端子に設定可能な最高電圧は、低電位側出力端子VOLの電圧となる。スイッチ502は出力制御器505からの第2のスイッチ信号を入力し、それに基づいて電池部303の低電位側出力端子VOLとリニアレギュレータ504の接続または遮断を行う。
