Abstract

Effektomformer særlig innrettet for å redusere innholdet av harmoniske på inngangen. Innholdet av harmoniske reduseres ved at effektomkoplingen sty- res på en hensiktsmessig måte, hvor strømforløpet i en omkoplet induktor (130, 230, 430) blir hovedsakelig iden- tisk med en likerettet versjon av spen- ningsforløpet for den påtrykte veksel- spenning til omformeren. De spennings- pulser som normalt vil oppstå ved omkop- lingen av induktoren i kretser som om- fatter spredningsinduktansen i en effekttransformator (120, 220) under- trykkes av kretser (144, 145) som mid- lertidig lagrer energien som spennings- pulsene representerer og deretter viderefører den lagrede energi til om- formerens utgang og belastning.
