Description
交流電源1からの三相交流電力は、R相ラインRL、S相ラインSLおよびT相ラインTLを介してR相コンバータ2R、S相コンバータ2SおよびT相コンバータ2Tにそれぞれ供給される。R相コンバータ2R、S相コンバータ2SおよびT相コンバータ2Tは三相コンバータを構成する。三相コンバータは、交流電源1から供給される三相交流電力を直流電力に変換し、直流正母線、直流負母線および直流中性点母線を介してU相インバータ3U、V相インバータ3VおよびW相インバータ3Wにそれぞれ供給する。
図6は、U相電圧VUとIGBT素子Q1U〜Q4Uのオンオフとの関係を示す波形図である。U相電圧VUは、制御回路7において交流電源1から電力変換装置100に入力される電力を基に計算される、U相ラインから出力される電圧の目標電圧である。U相電圧VUと参照信号φ1U,φ2Uとの高低が比較され、その比較結果に基づいてIGBT素子Q1U〜Q4Uのオンオフの組合せが決定される。その結果、U相ラインULとU相インバータ3Uとの接続点の電圧をVOU、直流母線PL1,NL1、CL1の各々の電位をVp,Vc,Vnとすると、電圧VOUは、電圧Vp,Vc,Vnのいずれかに決定される。
次に、比較例による電力変換装置と対比しながら、本実施の形態による電力変換装置の作用効果について説明する。
図10は、本発明の実施の形態の変形例による電力変換装置101の構成を説明する回路図である。本変形例による電力変換装置101は、基本的に図1および図2に示した本実施の形態による電力変換装置100と、コンバータおよびインバータの主回路構造、および、コンバータおよびインバータで構成される基本構造は同じであるが、変換器ユニットの構成が異なっている。
