If the inverter is powering a device with a full wave bridge rectifier, is there really any difference between the two?
There are not many devices left around with such a simple input as for most products PFC has been mandated for many years and that is certainly waveform sensitive. I think modified sinewave has largely been consigned to the dustbin of history except for those offshore copycat manufacturers who know no better and the unfortunate unaware consumers who still buy them (presumably because they are dirt cheap).
Well.. I grew up with a "class" of electronics that today seems to be called as "vintage"...
Several devices from the top notch builders boasted the "
HI-FI" property which certainly would put them above the underclass cheapos...
A HI-FI device usually has a thing called "linearity" and devices with absolute noise ratings order of magnitude better than cheapos..
Careful construction, shielding and LINEAR (Yes.. linear PSUs
) where the linearity of components were top priority.. not price or size...
I was certainly spoiled with SANSUI.. AKAI.. Marantz.. and dozen others..
TODAY.. well today some hairy heads worried because their parents consumed too much and the wasteland landfill of resources are stinky more than ever...well today these HAIRY HEADS "MANDATE" .. the whole world to do things like using PFC SMPS... and ditching all linear things because they say digital is somewhat safer better whatever..
Truth is... there is no more noise crap than a PFC SMPS and a digitally made signal from a patented chip algo. sold 10x the price..
Crap is crap. Audio and video today are garbage non linear stuff.
sold as better for people without a clue about Hi-Fi.
I really miss the old HI-FI all Linear stuff..
I am spoiled... too much AC/DC TYA and JH on the woofers..
So TODAY it seems that SINE INVERTERS although still required by these PFC noise generators are becoming a very expensive luxury.. just because the audio garbage is already all digital and there is nothing linear left...
Still the SINE INVERTER with linear response should be useful..
And I really doubt that Angus will ditch his Marshall head tubes...
