Ešte k tej našej debate, objavil som na stránke QSC toto, http://www.qscaudio.com/support/library/papers/pl90wp.pdfv
zrejme z doby, keď PL9PFC vyrábali (vtedy to bol krok vpred, teraz už nie..).
Zujímavý je hlavne odsek "The power supply story" kde sú aj vety
"To accomplish this, we change the energy transfer from the usual
voltage mode to current mode."
"When combined with the outstanding efficiency of the
output stage, the result is approximately twice as much power
for average program material on a given amount of AC service"
Prekladať to nebudem, aby to nebolo špatne.
