Description
図1は、本発明の実施の形態1に係る電力変換装置101の構成例を示す図である。電力変換装置101は、交流電源1から供給される交流電力を直流電力に変換し、変換後の直流電力を、平滑コンデンサ2に並列接続される直流負荷7に出力する。直流負荷7は、例えば、LED(Light Emitting Diode)、バッテリなどが想定されるが、出力端子に回転機などの交流負荷が接続されたインバータであってもよいし、出力端子にLED、バッテリなどの直流負荷が接続されたDC(Direct Current)-DCコンバータであってもよい。なお、交流電源1は、直流電力を出力する直流電源、および直流電力を交流電力に変換するインバータからなる構成であってもよい。
実施の形態1の電力変換装置101では、整流回路41はスイッチング回路31,32の後段に配置されていた。実施の形態2では、電力変換装置101において、整流回路41に代えて、全波整流回路を交流電源1の後段に配置する場合について説明する。
実施の形態3では、電力変換装置101を冷凍サイクル適用機器に搭載した場合について説明する。冷凍サイクル適用機器については、例えば、空気調和機、冷凍装置などがある。実施の形態3では、具体的に、電力変換装置101を空気調和機に搭載した場合を例にして説明する。
