Description
図7に示すように、交流電源1は遮断器2を介して変圧器3の一次巻線に、変圧器3の二次巻線は交流−直流変換回路4の交流入力に、交流−直流変換回路4の直流出力は蓄電池5に接続される。このようなブロック構成における交流−直流変換回路4の各種回路構成例を図8〜図10に示す。
第3の発明においては、前記第1又は第2の発明における前記基本波周波数の3N(Nは1以上の整数)倍の数のパルスは、制御信号としての直流量とパルス幅変調のための搬送波から形成する。
各IGBTのオンオフ信号は、パルス幅を決めるための制御信号と搬送波を比較して得られる。ここで、交流出力の基本波の半周期毎に比較条件を変更することにより、交流出力として正負対象の交流電圧が得られる。R相IGBTのオンオフ波形とS相IGBTのオンオフ波形は120度位相をずらして得られる。T相IGBTのオンオフ波形はS相IGBTの波形を120度ずらして得られるが、ここでは省略している。
また、実施例では、制御信号として直流信号を用いた場合を示したが、正弦波や台形波を用いても実現可能である。直流信号を用いた場合には、高周波変圧器二次巻線電圧を整流後、平滑するためのフィルタ回路14を小型化できるメリットがある。
高周波変圧器では、高周波化に応じて磁性体(コア)の大きさが小さくなり、また磁性体に巻く巻線の巻回数が減少するため、漏れインダクタンスが減少する。このため、高周波変圧器の二次巻線に接続される整流回路6のダイオードの逆回復電流が大きくなり、損失が増加する課題が発生する。
ここで、リアクトルは変圧器と直列に挿入されておれば良いので、一次巻線と直列又は二次巻線と直列に接続すれば、同じ効果が得られる。
