Abstract
Description
∴dr=(Vdc-Vc)/(Vrec-Vc)…(5)
以下、上記手法を用いたことの効果を示す実施例を示す。
図6及び図7はシミュレーションによって得られる諸元の波形を示すグラフである。但し、仮想直流リンク電圧Vdcは整流電圧Vrecの波高値(300V)の1/√2(212V)に設定した。またコンデンサ電圧Vcは整流電圧Vrecよりも高くかつ一定(400V)としている(以下同様)。
図8及び図9は、シミュレーションによって、本実施の形態の手法に従って制御した場合の、諸元の波形を示すグラフである。図8は図6に対応した諸元の波形を示す。図9は、図7のうち最下段に示されたグラフを除いた諸元の波形を示す。但し、整流電圧Vrecの波高値を図6、図7と同様に300Vとし、仮想直流リンク電圧Vdcを整流電圧Vrecの波高値と等しくし、かつ整流電流irecの波形を正弦波の絶対値とした場合を示す。
さて、実施例1で説明したように、仮想直流リンク電圧Vdcが整流電圧Vrecよりも大きい場合、dz=0となる「充放電」期間が存在する。他方、この期間においてインバータ6が出力する電圧Vinvは直流電圧ではなく、交流電圧である。よって仮想直流リンク電圧Vdcが一定値を採る場合には、dz=0であっても電圧Vinvが交流を実現するために、インバータ6は零電圧ベクトルで動作することになる。
