Description
図1は、本発明の実施の形態1に係る電力変換装置の構成例を示すブロック図である。電力変換装置1は、電気鉄道車両(以下、電気車という)に搭載される。電力変換装置1は、入力電力を変換して出力する電力変換部11、例えば電気車の運転台から取得した運転指令ならびに電力変換部11の出力電流などに応じて電力変換部11を制御する通常制御部15、電力変換部11の出力電力が目標電力範囲内にない場合に電力変換部11における電力変換を停止する保護制御部16を備える。目標電力範囲は、電力変換部11の出力の目標値に応じて決定される。図1の例では、電力変換部11は、交流電力を直流電力に変換して出力するコンバータ12、フィルタコンデンサ13、フィルタコンデンサ13で平滑されたコンバータ12の出力電力を交流電力に変換して出力するインバータ14を備える。電力変換部11は、一方向の電力変換を行う回路構成でもよいし、双方向の電力変換を行う回路構成でもよい。電力変換部11の構成は、図1の例に限られず、電力変換部11として例えばDC−DC変換器(Direct-Current-to-Direct-Current Converter)を用いてもよい。
