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。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は三相インバータを構成する。三相インバータは、直流正母線、直流負母線および直流中性点母線を介して供給される直流電力を三相交流電力に変換する。三相インバータで生成された三相交流電力は、U相ラインUL、V相ラインVLおよびW相ラインWLを介して負荷4に供給される。
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。
